Modeling and design of children's clothing is one of the areas of applied art, designed along with its main purpose to help character education and development of the aesthetic taste of children. In the education of children is of great importance surrounding environment and mutual relations of people in contact with them. Therefore, it is very important that children's clothing was high ideological and artistic qualities.
The costume is beautiful, comfortable, appropriate to the purpose, not only contributes to the development of artistic taste, but also the education, skills, cleanliness, neatness, discipline, humility and other traits of character of the man of Communist society. Clothing is always associated with any human activity and can be used for a variety of purposes: aesthetic, psychological, social. Development of the child's skills of accuracy and cleanliness promotes the use of bibs and aprons, robes and white collar of the school uniform.School uniform develops a child's punctuality, smartness and discipline.
Children's clothes should be more comfortable, hygienic, beautiful and useful, must meet classes, games, children of different ages and, in addition, to be cost effective. 
The comfort and hygiene of clothing have an impact on physical development and health of children. Beauty and the content of children's clothes associated with the novelty and clarity of composition forms.
The practicality and efficiency of children's clothing is determined by the cost of the fabrics and finishing materials. The practicality and efficiency of children's clothing should be combined with hygienic and other requirements: light weight, thermal insulation properties, good air permeability, comfort in wear, able to undergo frequent washing, cleaning, Ironing. The appropriateness of clothing is that it is fit for purpose, use.
Like clothes for adults, baby clothes go in groups depending on the purpose, intended use and seasons. It is divided into summer, spring and autumn, winter. On the use of children's clothing is divided into domestic, sports and uniform. In the group of home clothes, in turn, distinguish home, casual, festive clothes. Sports clothing for different sports. There are also uniforms for students.
The process of modeling, principles of composition of clothes for children of different ages is basically the same as clothes for adults; it also used the primary form elements in different combinations, connected in a single whole various kinds of ties of the composition. 
The difference lies in the changing requirements to the forms of clothes in connection with its purpose and use, also change uniforms depending on the person. Consider the dependence of children's clothing.
1. Clothing, its shape depends on the shape of the human body. If an adult has a relatively stable figure, the child's body is constantly changing, change its proportions and parameters. Therefore clothing will depend on the changes of the shape. 
2. The shape of the garment depends on the age of the individual. Children's clothing also depends on the age of the sign. 
3. Uniforms depend on the form of a man. It is clear that children's clothing depends on this trait. You cannot copy children's clothing clothing for adults.
4. Uniforms depend on a variety of human activities. Children's activity different from the activities of an adult, means and form of children's clothes must be different from the clothes of the adults. 
5. Uniforms depend on the time of year, time of day, environment, places of human activity, as well as the forms of clothing adults. 
6. The shape of the garment depends on the fashion. Of course, children's clothing is also subject to fashion, but fashion for children's clothing is somewhat different from the fashion garments for adults. In our time for kids to develop their fashion different from the fashion for adults.
So when designing children's clothing, you cannot copy the dress form for adults. You must take into account age-specific groups of children, the purpose of clothing, its utility, efficiency, materials, finishes. One of the most important aspects determining the choice of geometric forms, the construction of the silhouette of children's clothing, are the proportions of the figure of the child.
In determining the proportions of a child's body different age groups, special attention should be paid to the ratio of the size of the head and torso, length of arms, legs and on the visual perception of the waist line which divides the figure of the child on the top and bottom. 
Children divided into five age groups: 
a nursery group To include children up to 3 years, sizes 20, 22, 24, 26. 
To preschool will include children ages 3 to 6 years, with sizes 28 and 30. 
To the Junior school group - children from 6 to 12 years with sizes 32, 34 and 36. 
To the older school group - children from 12 to 15 with sizes 38, 40, 42.
Teen group - children aged 15 to 17 years old with the dimensions 44 and 46. 
Basic sizes of clothes for nursery is considered to be 26, for preschool - 30, for Junior high school band - 34, for high school groups of 40, for a teenage party - 46 dimensions. Those taken by age groups of children basic dimensions make model clothing. 
The size of the nursery have two growth I and II, the rest of the clothing sizes for all groups have three growth I, II and III.
Pre-existing conditional division of a child's body in different age groups is not true. Conventionally considered the ratio of the length of the head equal to growth: for infants - 1 : 4 for children aged 2 years - 1 : 4,5 for the children of school age 5 years - 1 : 5,5 for preschool children 8 - 10 years - 1 : 6, for schoolchildren aged 12 - 14 years - 1 : 7, for teenagers 15 - 17 years - 1 : 7,5. 
According to anthropometric measurements of a large number of children of various age groups, the proportional relationship of head length to growth were slightly different (see table. 5).

In Fig. 130 shows a diagram of the proportionality of the physique of boys of different age groups. Schematic figures of boys based on the data of measurements of growth length from waist line to floor at the side, length from waist line to the knee. length from 7th cervical vertebra to the knee. Based on these measurements it is easy to calculate the length of the head, then find the ratio of head length to increase.

In Fig. 131 shows a diagram of proportionality physique for girls of different age groups. From the comparison of both schemes proportionality of a Constitution for boys and girls, you can see that the relation of head growth in the same age groups for girls and boys the same. The proportions do not vary with differences size. growth.The figure shows that in the group of 8 - 10 years in the amount of 34 the growth of girls - 131 cm and for males is 128 cm, in the group of adolescents in the amount of 46 the growth of girls is 161 cm and for males 167 cm, and still the ratio of head length to increase in both groups for girls and boys alike.

In the figure, sketch the old canons allow more expressive to interpret the figure of the child, as the great size of the head allows more to emphasize the difference the children's physique of the figure of an adult. When drawing sketches of adults, seek their figures to make elongated, slender, with long legs, high. Children, by contrast, draw a more short-legged with a big head etc. 
  Baby clothes nursery. Considering the clothes for the toddlers group, you need to focus on children's clothes up to 1 year. Figure baby has a ratio of head to length of the whole body as 1: 4, the neck is very short, the girth of hips, waist, chest and head are about the same, hands, feet and legs. At this age the child is lying, but gradually begins to sit, and by the end of the year and taking the first steps.
Clothing of children under 1 year should be very free and easy, easy to put on, to have a minimum number of seams. Closet baby is out of diapers, vests, blouse, apron, Onesie, bonnet, long dress coat-jacket or coat-bag. Undershirts with diaper and a blanket - basic things for baby to 5 - 6 months. Vests are short, not reaching to the abdomen, thin cotton fabrics or flannel. Tissue used smooth or bright colors and with a small figure. At neckline and bottom trim vests leg with a drawstring.When a child begins to sit independently, to stand and walk, the most comfortable clothing become long dresses and Romper.
Outerwear children up to 1 year - long coats in an envelope or fastened with Neshka hooded. Depending on the season they are made from different fabrics and insulated lining. For winter, the sleeves of such a coat do with gloves. 
Clothes for boys and girls at this age is no different, except for color. The color of clothing for boys - blue, girls - pink. 
Used materials: Jersey and cotton fabrics, Batiste, calico, flannel. Coloring fabrics mostly pastel - light pink, blue, yellow, green tone and white color.
On the coat uses cotton cloth (baize, velveton, knit fleece, soft plush) more practical dark colors: blue, red, green etc. 
Main finish - narrow lace, Rick-rack, lace, plain embroidery and applique. 

In Fig. 132 depicts the main closet baby up to 1 year. Shown here: Onesie, cap, bib, long shirt, Romper with jacket and coat-sleeve with a hood and sleeves.
1.5 - 2.5 years, the figure of the child has already the ratio of head length to increase, as 1 : 5, the neck short, convex belly, waist is not outlined; hands, short legs, long torso. At this age children move a lot, but their movements are insufficiently coordinated. So the clothes of children of this age should be free and comfortable. 
The range of clothes toddlers group is more varied and includes dresses, dress, blouses, day and night shirts, pants, aprons, bathrobes, jackets and blouses, coats, jumpsuits, onesies. Clothing for girls and boys of this age are different.
Clothing for girls and boys, flared or straight, rests exclusively on the shoulders, even the pants are held only on the straps. 
A full wardrobe of girls consists of long nightgowns or pajamas for sleeping, gowns or aprons bathrobes, onesies, coat, summer jacket, winter coat. Winter coats can be fur. 

In Fig. 133 show clothes girls: dress, jacket with blouse, sandy, winter coat, winter jacket, coat, hat and cloak with a hood and rain cover.
The boy's wardrobe consists of nightgowns or pajamas, day suit: shirts, trousers, short or long, jackets, sailor suits, Bathrobe and apron, Sandpiper, overalls; outerwear: coats, summer, spring, autumn, winter. The coat can be replaced with a comfortable warm suit. 

In Fig. 134 show clothes for boy toddlers: pajama night, day suit, consisting of shirt, short pant with shoulder straps and jackets, sailor suit, overalls with shirt, summer coat and winter coat with pocket trim and collar.
In this age of the figure is isolated in the following order: legs, feet, head, arms, hands. 
The visual articulation of the figure should be somewhat higher stomach or not doing. Length dress above the knees to give harmony to the figure of the child. Turn-down collars without stand and supine. Often collars are not doing at all, especially in dresses for girls. 
Avoid unnecessary partitioning of clothing with various undercuts, structural and decorative lines. The beauty of clothing is achieved through color, pattern of fabric is proportional to the solution details and finishes.
