I do not have a measuring tape. I ordered a small size. Probably because I am petite and may have needed an XS, the shirt is roomy. It covers my derriere, so it covers just a little more than the shirt modeled in the picture. You can wear it tucked in if you want. It is not a tapered shirt. It is beautiful and people have no idea that it is an expedition shirt. It does not let in the heat, so it should be worn in warmer temps. I hope this info helps!
