The bra is well made and functions well enough but alas... I was a 36 F prior to pregnancy and even the I is way too small in the cup. I have found that HotMilk 36 GG fits me best now.

I work in a lingerie boutique and I know how to properly size... unfortunately my shop doesn't carry nursing bras.

I bought both the H and the I cups in this bra and I'd say they are closer to DD or DDD when compared to most American sizing and D or E for most European brands.

Hope that helps!
