What Is a 36M in Other Brands?
Bra sizes are not standardized: the same label means different things brand to brand, so your 36M is a starting point, not a fixed size. A US 36M usually needs a 36N in Victoria’s Secret, maps to a 36J in a true-to-size UK brand like Panache, and stays a 36M in Wacoal.

Common questions
36M conversion questions
- What is a 36M in Victoria's Secret?
- Victoria's Secret cups run about a full cup small, so a standard US 36M usually needs a 36N there. If you already wear a 36M in Victoria's Secret, your size in a true-to-size brand is likely a cup smaller.
- Which brands keep a 36M the same?
- In true-to-size brands a US 36M stays a 36M: Wacoal, Panache, Glamorise, b.tempt'd, Maidenform, Fantasie, Gossard, Pour Moi, PrimaDonna, Marie Jo, Anita, Goddess. Fit can still vary by style, so treat the label as the starting point.
- Do UK brands size a 36M differently from US brands?
- UK brands label cups in a different sequence above D (D, DD, E, F, FF, G), so the same letters can mean different volumes. In a true-to-size UK brand like Panache, a US 36M is a 36J; the band number stays the same.
- What size replaces a 36M in brands that don't use cup sizes?
- SHEFIT, Kindred Bravely, ENELL, Under Armour, Nike size by their own charts (XS-XL or numeric) instead of band/cup, so a 36M doesn't carry over directly. Start from each brand's chart with your underbust and bust measurements.
