Great fit!

TallSlim Tees is exactly what I needed. I'm 6' 5" on a good day and 190 lbs so finding a shirt off the rack is impossible for me. Then to have it tailored is not really a reality. This WM shirt fits great.

WM Dress Shirt

Wonderful fit and look! Stays tucked in for us tall guys, but not to long to wear out either. Love them!

Slick design but not like the others on site

Shipping great at usual. I'm wearing the green one and the sleeves are not as long as the other long sleeve dress shirt on here. It's not super short but both are mediums. I know it said sizing numbers are close so I know it won't be 100% the same. Not worth going up a size though for me. No shirt pocket which I didn't notice till I got it. Overall I'll keep as it fits well in the body and sleeve length doesn't bother me being slightly shorter.


The pure cotton fabric is soft, light and flexible so that it will drape well on a long, slender frame while giving you a nice, crisp look.
