It’s so bad that my fiancée has some bras that say she’s a B cup and others that says she’s a D cup. In order to go bra shopping, you have to actually try them on to find out if they fit.
If I had to try on underwear to see if they fit, I might not bother with underwear at all!
They’re so hard to find. I have to buy all my shirts at Eddie Bauer because 1) I’m a dad and 2) they’re one of the only stores that regularly carry them.
