Hi, it says 100% cotton, machine wash cold. It's not see through because of the pattern, but you may need a camisole, I didn't use one, just depends on your preference. Also, it is around 28" long, (it's not a short blouse) and about 25" measurement from under the arms to the other side when laid flat. So, it's a good size and could be loose will not be tight. Susan Graver usually is very forgiving on the sizes, i.e. you can be larger or smaller than normal XL and wear this. There is an extra button sewn in the inside seam if needed. The buttons are really cute. The sleeves can be worn rolled up 3/4 length or long. I maybe wore this one time. twice at the most. I forgot to mention in original descriptions I do NOT smoke. thank you I hope this has helped.
Thank-You Laurie! That helped a lot...Iam 5'6 and about 150lbs. I like my tops a little loose...so I think it will fit great (when I get it tehe) Hope I do! Thank-You much
