I have never, ever, ever found a wireless bra/bralette that works for me. My band size is too small and my cup size is too big and I always just end up with a saggy uniboob or spilling out entirely.
This was a game changer! I’m comfortable wearing it on its own as a top, but it provides enough lift and support I can wear it under clothes as well. I will say it’s a bit warm to wear under clothes in the summer, but I’m sure it’ll be amazing for cooler days.
My bust is 42” and my band is 33” (I usually wear a US 34G/ UK 34F) and I opted for a Large. It fits very well and is very comfortable. However, if I wanted more compression for wearing under clothes I would definitely be able to wear a Medium.
The price is also extremely reasonable (imo) compared to what I pay for regular bras since I need a more speciality size.
