LOVED this top – of course I did. It’s a white blouse, have I ever met a white blouse I didn’t immediatley buy?! The answer is no. This one fits loose / relaxed but I went ahead with the large because I liked the fit across the chest. Non sheer but is lightweight, is just fine with a nude bra. I'm in the large of the Mango skort, it runs loose / generous in the waist. I've linked the Zara version as well. LTKFindsUnder50 LTKFindsUnder100
