In addition to the main measurement determine the distance between the legs at the level of the ankle. The design on the shape with X-shaped legs of the line of the buttocks, hips and waist are moved in a counterclockwise direction with centers at the points I, B and T (Fig. 15). 

To determine the amount of displacement of the lines of the buttocks, thighs, and waist from point lay To cut КК5 0.25 of measurements of the distance between the legs at the level of the ankle. 

The point K5 and I connect the auxiliary straight line. Perpendicular lines ЯК5 hold the line of the buttocks, hips and waist.

For determining the fold line from the point To the right lay the cut КК51 = 0,25КК5. A fold line is carried out through the points K51 and I to the intersection with the waist line at point T'. Point K51 N and connect with a straight line. A fold line is carried out vertically through the points T, K and N, if the pattern of the fabric in stripes or checks, and through the points T', K51 and N, if the fabric is plain. 

The width of the halves at the level of a line knee length in the first case, define the from point K51 and the second from point K.

 Changes in the design of the pants shown in the drawing by dashed lines. Build back halves produce similar to the construction of the rear halves of the pants on the figure with O-shaped legs. 

Unlike the design of the pants O-shaped legs point K5 and K51 have on the line of the right knee point To the side stepping of the slice.
