I was so pleased to see a tank with enough coverage to cover a racerback bra. After reading the one and only review at the time of my purchase that said “they run large”, I opted to order an XL and a L. I love the izzy and the earlier racerback style tanks both of which I wear as an under layer in a form fitting but not tight XL. In this tank the L is ample, not tight and the XL wears more like a tunic on me. I’m keeping both. To get an idea of fit I find it helpful to know weight size comparisons, so I’m covering a 205 lb pearish body, 38/40C, size 16-18. I also have an assortment of Remys XL, Laylas I prefer in a 1X; both are worn over a tank. I don’t think the Brooklyn is as well suited to this sort of layering but I will give it a go next winter, though it is awesome with a light jacket or shirt over and can be dressed up or down. Highly recommend this as well as my other purchases.
