Common questions about bra size across brands
- Why is my bra size different in every brand?
- Every brand uses its own patterns, materials, and fit philosophy, and many use different sizing systems (US, UK, EU). A 34DD is not a fixed volume — it means different things in Victoria’s Secret, Panache, and Wacoal. That is why a size that fits perfectly in one brand gapes or digs in another.
- Does Victoria’s Secret run small?
- Yes. Victoria’s Secret cups run about a full cup small, so a standard US 34DD shopper usually needs a 34DDD there. Put another way, if you wear a 34DD in Victoria’s Secret, your true size is closer to a 34D in a true-to-size brand like Wacoal.
- What is my UK size if I wear a US 34DD?
- A US 34DD maps to a UK 34DD in a true-to-size UK brand like Panache. The band stays the same; the cup letter sequence differs above D (UK goes D, DD, E, F, FF, G…), so the translation matters most for fuller cups.
- Which bra brands run true to size?
- Among the brands we track, Wacoal, Panache, Maidenform, and Glamorise run essentially true to size. Freya bands run slightly snug; Elomi and ThirdLove cups run slightly generous; Bali and Playtex bands run loose.
