What Is a 46K in Other Brands?
Bra sizes are not standardized: the same label means different things brand to brand, so your 46K is a starting point, not a fixed size. A US 46K usually needs a 46L in Victoria’s Secret, maps to a 46H in a true-to-size UK brand like Panache, and stays a 46K in Wacoal.

Common questions
46K conversion questions
- What is a 46K in Victoria's Secret?
- Victoria's Secret cups run about a full cup small, so a standard US 46K usually needs a 46L there. If you already wear a 46K in Victoria's Secret, your size in a true-to-size brand is likely a cup smaller.
- Which brands keep a 46K the same?
- In true-to-size brands a US 46K stays a 46K: 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 46K 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 46K is a 46H; the band number stays the same.
- What size replaces a 46K 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 46K doesn't carry over directly. Start from each brand's chart with your underbust and bust measurements.
