What to know about b.tempt'd labels
b.tempt'd, a Wacoal brand, labels its bras in US sizes. The size chart on its bra size calculator page covers bands 32 to 42 and cups A to DDD, then G: the brand writes G after DDD, not DDDD.
The chart is laid out by sister sizes: each diagonal holds sizes with about the same cup volume, such as 32C, 34B and 36A. Its calculator asks for two measurements taken over a bra, around the band and around the fullest part of the bust, both rounded up.
b.tempt'd bralettes come in letter sizes, XS to 2XL, which the brand matches to bra sizes: XS is 30 A/B, M is 34 B/C and 2XL is 40 B/C. Letter sizes are not in these tables.
How US sizes work
A US size is a band number and a cup letter. The band is an inch-based label (30, 32, 34…) shared with UK sizes. After D, most US brands go DD, DDD, G, H, I, J (some write DDDD for G, and a US G is a UK F), where UK cups go DD, E, F, FF, G, GG, H, HH, J. EU and French sizes number the band differently: a US 34 band is 75 in EU sizes and 90 in French sizes.
The b.tempt'd size range
According to the size chart of b.tempt'd (shopbtemptd.com, October 2026), b.tempt'd bras come in bands 32–42 (US) with cups up to G. The tables start at cup A. A given style can come in fewer sizes: check its product page.

b.tempt'd sizes: your questions
What does the b.tempt'd bra size chart cover?
b.tempt'd sizes are US sizes. According to b.tempt'd's size chart (shopbtemptd.com, October 2026), the range covers bands 32–42 and cups up to G. The tables above give each of them in EU, FR, UK and JP sizing; for example, a 34C from b.tempt'd is EU 75C, FR 90C, UK 34C and JP C75.
What is the b.tempt'd bra size range?
According to b.tempt'd's size chart (shopbtemptd.com, October 2026), the b.tempt'd range covers bands 32–42 (EU 70–95) and cups up to G (UK F). The tables start at cup A. A given style can come in fewer sizes: check its product page.
How does the b.tempt'd sister size chart work?
Sister sizes keep about the same cup volume on another band: one band down and one cup up, or one band up and one cup down. For a 34C from b.tempt'd, they are 32D and 36B. For sizes just outside the range, the sister-size table above gives the closest one inside it.
How do b.tempt'd bralette sizes match bra sizes?
b.tempt'd sells its bralettes in letter sizes and matches each one to bra sizes on its size chart: XS to 30 A/B, S to 32 A/B, M to 34 B/C, L to 36 B/C, XL to 38 B/C and 2XL to 40 B/C. A letter size has no band and cup of its own, so it is not in the tables above.
How do b.tempt'd sizes convert to UK sizes?
b.tempt'd uses US sizes. Converting to UK sizes: the band number stays the same; cups DDD → E and G → F, the other letters unchanged. For example, 34DDD becomes 34E.
Is there a b.tempt'd bra size calculator?
Yes: b.tempt'd has a bra size calculator on its website, linked below; it asks for a band and a bust measurement taken over a bra. The Cherry Size calculator works from your underbust and bust and gives a size estimate in US sizes and the other main systems; the tables above then give the US label to look for at b.tempt'd.
Is my b.tempt'd size the same as at other brands?
With the same measurements, the size that fits can change from brand to brand and from style to style, and the tables on this page convert labels only: they cannot show that difference. The Cherry Size app takes two measurements, underbust and bust, and tells you the size to try at b.tempt'd.
