Breakout bras fitting

If I order a Comexim bra from BOB, what size should I go with?
The last bra that would fit me now (I think) was 70G. Which would put me at a 32F. My underbust is still 28.5”, so I’m thinking I’d rather go with a 30 band.
What size would I need?

Also, I want to order a new for my friend. She’s 38 underbust and 49 bust. Which size would work for her?

  • My snug underbust measurement is 29" and I wear their 30 bands.

    Is that 70G Comexim sizing? If so then yes, that's roughly a 32F in BoB sizing.

    For your friend, I would try a 38J or 40GG. If she prefers a snugger band, she could try the 38; if not then the 40 should work. I think most people would prefer the 40?

  • wildflower_ so I don’t have to size up in the cup as it says on their website?
    I think I went with the 70 band because the 65 felt too tight.
    And the sizes, are you giving me the UK size or US size? 🥴
    I think what confuses me about their sizing is that they have the US size and the UK size.
