We have a simplified sizing system for this bikini top - why? Because the width can be individually adjusted here, so only the cup size is relevant. That means it doesn't matter whether you wear our bralettes M70 or M85 - the M cup is the same with us, and you can adjust the width of this top to your individual comfort width.
Our cups are available in S, M, L and XL, whereby the cup sizes can be converted to "normal" bra sizes as follows:
S cup: fits very well for A and smaller B cups (recommended for 70A, 75A, 80A, 70B)
M cup: fits very well for B and smaller C cups (recommended for 80A, 75B, 80B, 70C, 75C)
L cup: fits very well for C and D cups (recommended for 85B, 75C, 80C, 70D, 75D, 70E, possibly 80D)
XL cup: fits very well from D cups (recommended for 70F, 75E, 80D, 85C, 90B, 95A)
With our non-wired cups, which softly adapt to the shape of the breast, it can also happen that two different cup sizes fit someone well, but the smaller one creates more detail, the larger one "packs in" more - around 75C - here it really depends individual well-being!
If you are unsure, you are also very welcome to contact us (e.g. at firstname.lastname@example.org), we have already accommodated a lot of breasts in our bikini tops <3
