First to give you an idea of how sizes run, I am 5'5" and weigh 135 lbs. I ordered a large and it was too big-especially around the waist.  It has a little bit of an A shape to it-wider at the bottom. I clicked the "return this item" link so I could return it, and Amazon said to keep it since I was a loyal customer, etc.  So I thought I'd give it to someone who is a little larger than I am.  But I put it in the wash, washed it in warm water and dried on low heat in the dryer, and after it came out it fit-but still kind of wide at the bottom.  It might make a good 2nd trimester maternity shirt.

I personally like the material-it's like a 4 or 5 oz. cotton-like the "old" t-shirts; not like the paper thin ones they sell now. I have the pink; it's a really pretty color if you like hot pink.
