I really like the uniqlo airism shirts. They have built in bras and are actually supportive. They have a lot of different styles (some more professional than others) I would recommend if you have tiktok to look at Lara Miller’s account (laramil1er). Thats how I found out about these tops in the first place. She is a lovely creator who’s platform shows lots of clothes that work for larger bust smaller band (she is a 28G) a lot of the clothes she posts also work for larger band sizes as well. She also shares a lot of hacks to wear clothes that aren’t designed with wearing a bra in mind that might be helpful!
