What Is a 38N in Other Brands?
Bra sizes are not standardized: the same label means different things brand to brand, so your 38N is a starting point, not a fixed size. A US 38N usually needs a 38N in Victoria’s Secret, maps to a 38JJ in a true-to-size UK brand like Panache, and stays a 38N in Wacoal.

Common questions
38N conversion questions
- What is a 38N in Victoria's Secret?
- Victoria's Secret cups run about a full cup small, so a standard US 38N usually needs a 38N there. If you already wear a 38N in Victoria's Secret, your size in a true-to-size brand is likely a cup smaller.
- Which brands keep a 38N the same?
- In true-to-size brands a US 38N stays a 38N: 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 38N 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 38N is a 38JJ; the band number stays the same.
- What size replaces a 38N 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 38N doesn't carry over directly. Start from each brand's chart with your underbust and bust measurements.
