Because Comexim is a Polish brand, the cup sizing is not going to exactly correspond to traditional UK brands (like Panache, Freya, Elomi, Curvy Kate, etc). The size listed IS UK sizing, but Comexim bras run about two cup sizes small compared to these UK brands. SO, for a fit that is technically correct and gives adequate wire coverage on the sides, you should order two cup sizes larger than you do in your regular UK styles. For a little extra oomph, only order up one cup size, especially if you have an empty/shallow upper bust. This will give you more volume and a little less side coverage.
The Comexim Bubbles Padded Plunge Underwire Bra (CMBUBBLE) has a high, rounded shape with a bright and vibrant colorful polka-dot print. This padded bra defines and lifts, and adjustable shoulder straps let you customize your look. Pair with the Comexim Bubbles Matching Brazilian Thong (CMBUBBLEMT), sold separately, for fun and flirty matching style.
