Comexim uses UK band and cup sizes, but runs small in the cup.
UK band sizes are the same as US bands, but the cup letters are different. Because Comexim runs very small in the cup, we recommend going up 1 cup size compared to other brands for a cleavage boosting fit. E.g., if you usually wear 34DDD, try Comexim in 34G. If you prefer a fuller coverage fit, go up two cup sizes.
We provide the US size equivalent first, and if it is different, this is followed by the Comexim native size (the size that you will see on the tag) in parenthesis.

A lightweight yet ultra-supportive sheer half cup style for when you're feeling blue!
Built to elevate, center, and create effortless cleavage without padding, this half-cup draws the bust together for a smooth, rounded shape.
Highlights
Cups: Three-part, low-coverage, half-cup structure with dual vertical seams, short underwires, and medium-rise gore ensures optimal lift and shaping. Dual-layered, firm, semi-sheer mesh provides streamlined support. The outer layer is covered with an all-over diamond, fishnet-like pattern that provides some nipple coverage and a textured look while maintaining a smooth profile. A thick, scalloped navy trim at the top of the cups elevates this style with a luxurious feel.
Band: True-to-size, stretchy yet supportive band is made of a double layered semi-sheer powermesh finished with barely-there scalloped edges.
Straps: Wide‑set, fully adjustable straps with some stretch.
Best For:
Even or Top Fullness, and Implants: the open cup shape with vertical seaming best suits rounded shapes with some fullness on top. A great option for high-profile implants.
Narrow Rib Cages and Full Busts: narrow, short wires prevent underarm poking.
FIT NOTES
The Comexim brand runs small in the cup and this style runs extra small. Size up 2 cup sizes compared to your typical size in other (non-Polish) brands.
For example, if you typically wear a 34DDD/F, try this style in 34H.
The band is medium firm and runs true to size - keep your typical (non-Polish) band size.
For those familiar with the fit of other Comexim styles: the Tanzanit's 3HC cups run shallower than Comexim's Padded Plunge styles like the Elena and Basic—size up one cup compared to your size in the Padded Plunge styles.
The Tanzanit also runs 2 cup sizes smaller than the MIARA Y Sheer Half Cup - keep the same band size but go up 2 cup sizes vs your size in the MIARA Y.
Note: Comexim bras at Miseczki are marked with UK sizing, which uses the same band convention, but different cup letters, than US sizing.

I was on the hunt for this beautiful navy bra and so happy to find it from an English speaking retailer! Karina was so helpful and quick determining size in a few emails from photos I sent. My Goldilocks fit is the 26GG (26G was bubbling and tips of areolas showing, 26H the wires were uncomfortably wide and had room to move to less height over nips). I’m 100lbs, have a 25.5” rib cage and round high profile implants that are 34”. 26GG seems to be my size in most Comexim, give or take. In the similar Miara Y Sheer Half Cup (an even better fit for my deep cup needing implants!) I wear a 26H (26FF UK)
