What Is a 42L in Other Brands?
Bra sizes are not standardized: the same label means different things brand to brand, so your 42L is a starting point, not a fixed size. A US 42L usually needs a 42M in Victoria’s Secret, maps to a 42HH in a true-to-size UK brand like Panache, and stays a 42L in Wacoal.

Common questions
42L conversion questions
- What is a 42L in Victoria's Secret?
- Victoria's Secret cups run about a full cup small, so a standard US 42L usually needs a 42M there. If you already wear a 42L in Victoria's Secret, your size in a true-to-size brand is likely a cup smaller.
- Which brands keep a 42L the same?
- In true-to-size brands a US 42L stays a 42L: 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 42L 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 42L is a 42HH; the band number stays the same.
- What size replaces a 42L 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 42L doesn't carry over directly. Start from each brand's chart with your underbust and bust measurements.
