Very cute, nice fit. Im 5'4" and 115 lbs and xs fits me perfectly. Im usually a s or xs so if in doubt, size down. Not sure what to do with this skirt however, other than casual wear. Ive never hiked in a skirt, so maybe that's a possibility, but I have run in a running skirt and agree that it is not ideal for that. Material isnt particularly flowy or lightweight. It really is like high quality yoga pant material mAde into a skort. Altho Im not sure Id wear it for yoga either. Still debating whether or not to keep it. Pockets are a plus however.
