The Skims Size Chart, Interactive

Skims splits its sizing personality: alpha sizes on most styles, a proper numbered chart on the underwire lines. This page maps the numbered grid: the one where a measured size means something exact.

The native chart

Every Skims size: tap for conversions

Numbered sizing applies to underwire lines; alpha (XXS–4X) elsewhere.

Two measurements in

Your size at Skims

Same published math as the calculator (snug measure, no +4) then translated into Skims’s native notation and checked against the real chart above, which lights up your cell.

Reading it

How Skims sizing reads

Skims’s chart reads band-then-cup in inches and US letters: the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation.

The alpha wrinkle: Most Skims bras sell in alpha sizes (XXS–4X); this chart covers the numbered underwire lines. Alpha sizes bundle several band-and-cup combinations into each letter: the product page's own alpha map decides, and between alpha sizes, size for the band.

How Skims runs

BandBands run true to size: start with your measured band on the loosest hook.
CupCups grade true to the measured difference.
Wire & strapsWires are average width for the system. Straps: Standard.
Quirk 1Alpha sizes compress; support above a D comes only from the numbered lines
Quirk 2Alpha size follows the ribcage: a 34DD and a 34B may share a size in a stretch bralette
Quirk 3Numbered range reaches H but availability varies by style

Honest edges

Where this chart ends

For deep cups beyond H, UK specialists (Elomi, Panache) continue the alphabet. And if a symptom (riding band, gaping cup, poking wire) sent you size-hunting, the fix guides decode it before you spend anything.

What sizing system does Skims use?

Native US sizing (it reads band-then-cup in inches and US letters) the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation. The interactive chart above shows every size with its US, UK, EU and FR equivalents.

What sizes does Skims carry?

32–46 bands with A–H cups in US notation. 64 sizes in the core chart. Numbered sizing applies to underwire lines; alpha (XXS–4X) elsewhere.

What if Skims doesn't make my size?

For deep cups beyond H, UK specialists (Elomi, Panache) continue the alphabet. Sister sizes (same volume, different band) sometimes bridge a one-band gap: the calculator above tries them automatically before giving up.
