Comexim

Comexim, a Polish brand, has had a huge surge in popularity for those narrow-rooted ladies all over the world. They make cups A-N (roughly a UK B-HH/J) on bands 60-90 (28-40), and have been known to custom make 55 (26) bands, make gores taller, and convert any bra into a nursing bra. Their sizing system is a bit different, as they have an HH cup instead of an I cup, but they still have 2cm cup intervals.

Style: Green Velvet

Style: Red Flower

Style: Florence

 Their padded bras are pretty strictly plunge, so if you have soft breasts, you could ask for the gore to be heightened, or can try a soft cup balcony like this one:

Style: Noa

Style: Geisha

Comexim even carries some swimwear, like this SS13 bikini. (And it looks a bit velvety; I would not stop touching it if I had it on.)

Style: Haiti Bikini

Style: Summer Time

Style: Paradise

Style: Aisha
