From your fit pics, the pair looks too tight and uncomfortable as per my taste, but its your call that really matters. I would usually choose a pair that is not too uncomfortable even to start with. You can expect .5 inch stretch in the thigh and a little more in the hips.
Here are some fit pics after 2 months of reasonable use in rotation with other pairs. I cant wait to machine wash this pair. I usually wait for a few months for the creases to set in before a machine wash to clean up all the starch and enjoy the smoothness.
Btw, this pair is very breathable, not too bad for summers at all.
