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. Keep your normal band size. This is the padded plunge shape from Comexim, which gives close-set wires between the breasts (great for women with a concave rib cage or narrow breasts) and narrow wire shape (great for women with protruding ribs, since the wires don't rest against the ribs as wide like some of the broader wired bras).The padded plunge shape gives excellent boost and forward shaping, so you get a full, plump look if you have softer tissue, heavier tissue, or if you're just naturally very full/round on top. If you have less upper mass, you may not get quite such a full look on top, BUT you will still be lifted and fill the cups well. You'll just be more contained than someone that has more mass up top.
The Comexim Gloria Padded Plunge Underwire Bra (CMGLORIA) is a sultry padded black bra with plenty of uplift and separation alongside a beautifully luxurious design. The multi-section cups define and separate thanks to the higher center front, while padding, a strong underwire, and strong side bands provide support and uplift for comfortable daily wear. Smooth cups won't show under most clothing, and the unique double-strap detail at back band shows a hint of unexpected skin. Features fully-adjustable straps with metal ring detail and Art Deco-inspired pattern.
