Abstract: Based on the three-dimensional cutting pattern design of full-cup bra for the disc shape breast,four kinds of shapes of women’s breast———disc,hemisphere,taper and flagging shapes as well as the influence of the elastic fabric on the bra pattern were analyzed.Research was conducted to improve the fitting of bra patterns for each kind of breast figures: altering the pattern size of the lower or upper cup,or altering the back pattern size,the bra will have the effect of supporting up the breasts and making their contours fully displayed.It makes the bra more perfect in pattern structure,more comfortable to wear,and graceful in figure,all these are desired by the female.
