G Bra Cup Size (Your UCS is either a D4 or a D6 )

Your G cup size can be a little tricky between different brands.  If you're a G cup size in EU brands like Chantelle, Empreiente, Prima Donna, Anita, Simone Perele, you are also a G cup size in USA brands like Wacoal, Bali, Natori, and Vanity Fair (formerly called a DDDD cup size).  However, you are also an F cup size in UK brands like Elomi, Freya, Panache, Fantasie, and Curvy Kate. 

But..., if you're a G cup size in UK brands, you are also an I cup size in both US brands and EU brands. A UK G cup size is 2 cup sizes larger than a EU and US G cup size.

At HerRoom, we make finding everything availabe in your cup size easy with our exclusive Universal Cup Sizing (UCS).
