micoach is all you need to get the results you want.
I do like these. They are a bit long in the crotch area, and a bit too short for my 5'3", 135 lb frame. However, they are good quality. There is no cozy inside, and are fairly thin. The picture is true to how they look on.
For sizing i went off the pics illustrated for the jacket & got a medium but found the jacket a little too tight for my liking & also slightly short. Great looking jacket & if you like it tight on you then great but too tight for me...my lad wins again & gets a new top!
This is a good quality t.shirt but if you are ordering I would go a size down. I'm normally a 12 but think a 10 or possibly an 8, as it is supposed to be tight fitting, would have been better. Happy with the customer service though.
