REAL REVIEW FROM ANOTHER BOUTIQUE OWNER: I got my Bralettes in late last week & they ARE AMAZING! 👏🏻Coming from a plus size lady! I’m normally a XL/1X and 14w/16w I’m jeans... THESE FIT SO GOOD!I’m a 42C in bras, I’m wearing the L/XL and they had a SO SO SO MUCH STRETCH!!It could easily fit a size bigger than me! Which is so hard to find a Bralette that fits so good!
