First of all, these pants are FULLY lined like all the way down. And that is SO nice when it comes to white pants. These are not linen, they’re a flowy fabric with a touch of a sheen to them. VERY comfortable but chic as well. I am in the large and they fit perfectly for me. The drawstring is adjustable but I wouldn’t say it would make that much of a difference with sizing. This sweater top is so lightweight and airy. Really nice option for summer. However it does run big – I am in the large here and a medium would fit me best. It’s just a bit big overall. I love it with the pants, as well! LTKSummerEdit LTKOver40 LTKFindsUnder100
