Loose overall is 100% cotton, nice and lightweight to keep you cool. Shorts cuff is sewn in a few spots to keep in place. Long ties can be tied many ways, tighter or looser based on where you want the bib to stop in front. I have these and i wear with pockets in back or front, with a tee or just a bralette. Can also work as a swim cover and beach wear! So practical but still VERY stylish, works unisex too. Small model is wearing size M -fabric does not stretch. Sale is overall only -all sales final so please ask any questions before purchasing. All meas taken flat and unstretched. Please let pics guide you to where the measurements are for. Pics show M meas, but same areas will apply for other sizes. Hard to say where hip will fall -will vary based on how high you tie the bib & straps.
