Bras generally come with symmetrical cups that are similar in size, shape, and mold; this is why women with non-similar breasts find it difficult to choose the right bra. But, this isn’t an issue that can’t be resolved.
Try a Padded Bra - Bras that come with foamed padding usually helps you with a rounded and a fuller bust shape compared to the unlined ones. Especially, when it comes to daily wear T-shirts and flimsy tops where breast shape will be more evident, going in for padded bras will be the best choice.
Bras with Removable Padding - There are bras that come with inner pockets to insert and remove foamed pads as and when required. You can either remove the padding on one side to bring symmetry or use two inserts on the breast that is smaller in size.
Sports Bras and Cami Bras are the best bets - Slip-on intimates don’t have separate cups and hence offer a uni-boob appearance. The elastane that goes into the making of these intimates provides the essential support that is needed, unlike a regular bra that depends on its cups for the same.
