42G Bras, Lingerie, and Swimwear | 42G Bra Size

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).

Search 42D4 to see everything that comes in your G, DDDD, and F cup sizes.

Search 42D6 to see everything that comes in your G, and I cup sizes.
