I love, love the material of this blouse - it's so smooth and soft and weightless, very airy as well so you can wear as sun/mosquito protection and look stylish. I ordered medium, (5'9, 140 lbs) and it's just enough loose fit to wear another layer underneath (I ordered white, and while I would not say it's a complete see-through, you might consider wearing a tank top underneath). It has thumb holes which I really love. Very happy with this product, recommended.Shirt fits perfect in size. Flexible so you can move. Soft silky material. This type of fabric shows all your bumps and rolls. If you wear a tank top it helps.I absolutely love the weight of the fabric and the color contrast and the fit is spot on.
