For a slim (not skinny) fit we suggest fitting true to size options. They tapper skinny towards the ankle like all joggers should and are cut about 3" shorter than a normal pant inseam. These are more of a spring and summer ankle flashers than a pant.
If you like it skinny, the elastic waste, and stretchy fabric makes it easy to size down for a true skinny fit.
I'm 6' 190lbs with an athletic build. I have both M and L sizes in my closet. M for a skinny fit, or a L for the more relaxed slim fit. I like em both.
