These are the shorts I'm shopping for above ^^^

I have thighs kind of like that, and personally I try to avoid super short shorts, like the kind that barely cover the butt because I find they ride up and make the thighs look larger. Also, super tight shorts will make them look larger as well.
Anything other than those 2 things should be fine but I find shorts that hit just above mid thigh are the most flattering for me.
