Tank
Our tanks are true to size. If you have bigger boobs, like a DDD or more, I would size up. It won't fit that different, and it just gives you an extra bit of coverage on the boobs. The model in the photo shoot is wearing a small, and the model wearing the bra and bloomer set is wearing an XS.
Bloomers
Our bloomers are true to size. If you want a baggier fit, size up! I personally like to wear these as my everyday undies so I get them true to size. UGHHH they're so comfy I hope you like them!!! Here's a chart:
US size | UK size | Buttercup size |
0 - 2 | 2 - 4 | XS |
4 | 6 | S |
6 | 8 | M |
8 | 10 | L |
10 | 12 | XL |
