What Is a 50F in Other Brands?
Bra sizes are not standardized: the same label means different things brand to brand, so your 50F is a starting point, not a fixed size. A US 50F usually needs a 50G in Victoria’s Secret, maps to a 50E in a true-to-size UK brand like Panache, and stays a 50DDD in Wacoal.

Common questions
50F conversion questions
- What is a 50F in Victoria's Secret?
- Victoria's Secret cups run about a full cup small, so a standard US 50F usually needs a 50G there. If you already wear a 50F in Victoria's Secret, your size in a true-to-size brand is likely a cup smaller.
- Which brands keep a 50F the same?
- In true-to-size brands a US 50F stays a 50F: 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 50F 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 50F is a 50E; the band number stays the same.
- What size replaces a 50F 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 50F doesn't carry over directly. Start from each brand's chart with your underbust and bust measurements.
