I can wear traditional mens buttonfly Levi's and figured out my middle son's BDU's fit me. I am built more like a slim man when it comes to my waist and hips. When I wear my Levi's low-rise jeans it's basically my quads that keep them on.
Shirts...ugh! I have broad shoulders and larger bi's than most women's clothes account for, but men's small sort of fit. So I tend to live in tanks and Levi's or shorts. Almost all of my tech clothing for the trail is from the men's department of my favorite outdoors outfitters.
