PG gear ain't small at all! I'm a girl and ain't that skinny either (uk 8-10), finally bought the black tee with the paisley logo last weekend after the PG party, got a size xs and it actually runs a little big! I've even seen XXL sizes (I actually struggled while trying to find an xs).
I'd give it a go; I'm sure you'll find a size that fits you and you won't be disappointed, PG stuff is amazing
