Question 1

My son's 6 ft to 6 ft 2, and 140 lbs, large in undershirts and small in underwear. what size should i order for him?

Accepted Answer

I'm 6'4" 180lbs, and was always like that as a teenager- large tops, small or sometimes medium bottoms. I filled out in my 20s-30s when I stopped skipping leg days, to be more like L bottoms, XL tops. Now, in my 40s, I'm a L top and 34"w x36L in Balmain, Gucci, Mike Amiri, Raf Simons, Ralph Lauren, Dulce & Cabana etc., actually I have an aunt who detests $2000+ for jeans and sends me Levi's every Christmas to make a point. 32 waist (well hips actually idk who wears jeans up that high but if it did I could actually wear a 28" or 30" but then I would need a 40"-42"L LOL 
Shop clerk, "Can I help you with anything sir? Mmm yes, I'd like to try on a 28Wx42L in these dodgy looking Walmart jeans please shop keep, I cannot seem to find anything on the rack 🤔?) 
Crazy. So I tried XL. Ha. No way. Maybe 1 leg in each of 2 pair, otherwise, mmmno. XXL was too tight (stretched too thin in my glutes, thighs & calves, and still too short -- looked like I was waiting for the flood. 3XL made all the difference. If he's 6'2" but under a buck fifty, XXL will give him a good fit + room to grow. I should have considered that - if I was 2 inches taller ( 6'6" ) these would be too short and then all the extra material that fits me as I am, would be higher up and therefore too small. So, long story short, XXL now [✓] If you anticipate him growing much more in the near future: 3XL. Good luck! 👖👕🧦🧤🧥🧣🛍️🩲🧢👟🥾⌚💎🎒👜👓🕶️

Question 2

My husband is 6 ft 155 lbs. so tall and skinny. What size should I get him?

Accepted Answer

My husband is 5' 8'" and weighs up to 175 at his heaviest.  I got a medium for him and the length was just perfect.  As the other person said, they fit like tights or like a good athletic shirt that I can't name but will stretch depending on the size of the person.  I would think a large would be needed for his height.

Question 3

Im 6ft 5 and 219 what size should i get?

Accepted Answer

I'm 6 2", 230 and I got xxl.    If I bought again I'd get xxxl.    They run small, and are a stretchy material that's comfortable but really hugs the skin. Pretty nice overall, though.
