Okay let’s talk this skirt first! This one runs kind of big – this is the medium and it’s very stretchy and loose at the waist. I would say size down if you are in between sizes. It IS fully lined and you can’t see a thing through this skirt! PLUS there are POCKETS. This one is a big yes for me! Loved this tee too and kind of obsessed with how well it looks with this skirt. Now this shirt is a thicker cotton, holds its shape well, boxier fit. I am in the medium and it does fit true to size but I would suggest that if you have bigger boobs and want an even looser fit, go up one size. LTKxMadewell
