I am 55 & a half and weigh 196lbs. I wear a 38C & normally a size 12/14. I have an athletic build and my chest is average but my rear is almost non existent, (its the truth ). I was initially confused by all the reviews, as everyone states how much they love it and what size they purchased; but fail to tell us what size they are. So i ordered an XXL & although it did fit, it swallowed me & the arms were about an inch too long. I ordered a L and it fit perfectly. There is plenty of material play in the front to be flowy & the sleeves were perfect length. I am happy with this product. It is very thin - almost sheer - but perfectly lightweight to wear over a dress or casual top with jeans. I purchaed the Green one to wear to the St Patricks Day festivities in Savannah this weekend. The green matches perfectly with Green Chuck Taylor Converse sneakers, if you're confused about the shade.
