How Should a 40A Bra Style Fit?
There’s one general rule that applies to all bras, and bra size 40A is no different - if it feels good and looks good, then it fits! Make sure that you can barely feel the underwire of your bra and that it doesn’t poke into the skin. The straps should sit comfortably on your shoulders without digging in or sliding down. Perfect-fitting cups will feel smooth and supportive with no gaping. All in all, the bra should be hugging you in all the right places without feeling too tight.
