It is hard to say really, I am 5' tall and 150 lbs. I carry my weight as a BBB bust, belly, and bottom.....in other words I am apple shaped. My bust is a 42 DD and the PL fit just fine. I also omit padded bras, and may times pair my sundresses with a "colored" athletic bra so some of it (small line at the neck, and shoulders) shows as an accent.
Hope this helped.
