How UK bra sizing works
UK sizing uses familiar inch-based band numbers, but the cup sequence is different from many US brands after DD. The UK sequence is especially important when shopping brands such as Panache, Freya, Fantasie, and Bravissimo.
When to use a UK bra size chart
Use the UK chart when a brand lists cups such as E, F, FF, G, or GG. If the label says DDD, it may be using US sizing instead.
