Hello friends, by God, we sew a double-breasted dress very easily, but we can make a cardigan if we want this dress pattern, the formula is very easy hip /4 +1, since I work with a flexible fabric with lycra, I did not give seam allowances in the side seams, but if you work with an inelastic fabric, there will be plenty of space. give the share of at least +2 cm ... I recommend you to choose flexible fabrics that are compatible with the model I am working on, size 44/46 ... STAY WITH LOVE
