Wacoal Response: We apologize for the negative experience you’ve encountered. The cup construction and coverage of style 85121 is not as full as the 855186. Is the center panel on the bra flat against your chest or is there space or breast tissue in between your chest wall and the center panel? If it is not laying the flat, then the cup is too small and the breast tissue is pushing the cups away from your chest straining the fabric. This could cause the mesh to tear. So if you are a 34C in 855186 you may need a 34D in 85121 as this bra has less cup capacity than 855186.
