Skims Bra Size Chart & Sizing
Alpha-sized shapewear-adjacent bras and bralettes, plus a numbered underwire range: the sizing story is knowing which you're buying.
Skims in numbers
Skims began in shapewear and expanded into bras with two logics: alpha-sized soft bras and bralettes (XXS to 4X), and numbered underwire and t-shirt bras in bra sizes. The alpha styles fit the ribcage and compress rather than support; the numbered styles fit like conventional bras.
Your measured size in Skims
How this is computed: your US size read straight onto the US label, then adjusted for how Skims typically grades: true bands, true cups. This brand sells many styles in alpha sizes (S/M/L or numeric athletic sizes) that fit the ribcage rather than the cup: the conversion below applies to its numbered bra-sized styles; for alpha styles use the brand grid and expect support to fall off above a C or D.
Where Skims sits on the size grid
Cups Numbered lines A–H. Not every band–cup combination exists; the largest cups usually appear on mid-range bands only.
Best for:
- Stretch bralettes and lounge
- Smoothing under clothes
- Numbered t-shirt bras in mainstream sizes

Coverage is approximate to the brand's core collections; the largest cups typically exist on mid-range bands only. US DDD is written DDD here.
Does Skims run small or big?
Skims bands run true to size across US bands 32–46: start with your measured band on the loosest hook, and expect it to feel snug for the first week if you are coming from an add-inches size.
Skims cups grade true to the measured difference from A to H: a gap or overflow in the measured letter is a shape signal, so change the cut before the size.
Skims wires are average width for the US system. Straps: Standard.
