I'm in the difficult middle ground when it comes to clothes shopping....too big for the regular stores, too small for the "big" stores.
Generally an 18, sometimes a 16....depends on the cut.
My issue is that I have a very large butt, that sits rather high (okay....it's the truth

) and anything that fits my ass does NOT fit my waist, so I tend to favor dresses and skirts.
I go with curvy.
