Size 176-100-88, completeness second. 
Measurements (measurements) to calculate cm: 

SSH = 20,5 Dt.C=45,5 
SG = 50 Di = 76 
PT = 44 SHP = 15,5 
SV = 52 PD = 64 
Dt.p = 55,6 Op = 32 
CC = 19,2 CDF.h = 21,5 
SHS = 20,4 

Allowances for free customized fit, see: 

PG = 7 PD.t.p = 1,4 
PT = 7 PD.t.s = 1 
Pb = 4,5 PH.throats.s = 1,5 
PS.Ave = 2.5.n = 10

the distribution of the measurements at SG sites, see:
SG = SS + Sh + SIMP, where SIMP = SG - RC - CG = 50 - 20,4 - 19,2 = 10,4. 

The width of the sleeve under the armhole desired:
Sruc.x = (Op.on) /2 = (32+ 10) /2 = 21 see 

The distribution of the common stock of PSH.C = 7.1 cm areas cm: width backless PN.C = 1,5; the area of the openings PU.or = 4,6; width of chest PN.g = 1. 

Calculation of posture: 
Dt.p - Dt.C = 45 - 45,5 = - 0.5 cm.
