Selected (1):
F Bra Cup Size (Your UCS is either a D3 or a D4 )
Your F cup size can be a little tricky. If you are an F cup size in EU brands like Chantelle, Empreiente, Prima Donna, Anita, Simone Perele, and others, you are also a DDD cup size in US brands like Wacoal, Bali, Natori, and Vanity Fair, and an E cup in UK brands like Elomi, Freya, and Panache.
And... if you're an F cup size in UK brands, you are also a G cup size in both US brands (formerly the DDDD cup size) and EU brands.
At HerRoom, it's easy to combine all your cup sizes into one simple search by using our exclusive Universal Cup Sizing (UCS).
Search 40D3 and see everything that comes in your F, DDD, and E cup sizes.
Search 40D4 and see everything that comes in your F, DDDD, and G cup sizes.
