Mix Print Straight Leg Pants

I am 5’5, about 155 lbs and normally a size 6 or 8 and a consistent size medium in pants. Purchase the medium based on the size chart and I could not get them close to be able to zip. The legs fit fine. Not that my butt is huge, but I noticed they are not meant for any woman who has more of an athletic, round rear end. I would probably have to go up to size xl to get them to fit properly but then they will be too large in the legs. This is the second time I have purchased from this brand, but 1st time in pants. Their tops in medium fits me just fine. I am not sure if this brand runs small overall, but I will need to try on in the store next time before ordering online. Lesson learned, you cannot trust their size chart. My waist is a 29, usually I wear a 31 inch inseam, and an hourglass shape…and these are just a big no.
