I just got these in the mail today, and I am going to exchange them for the next size up. I am 5'7" and about 170 lbs, but I carry most of my weight in my hips and butt. These scrubs are really cute, but kind of snug in the hip/butt area. I could probably manage with the size I got (Medium Tall), but I don't want to risk splitting the seam. The length of the pants is good because I have longer legs and I always buy tall scrubs. If you are a little curvier, I would recommend going a size up for some comfort room.
I can't tell you how happy I was to find the long length a perfect fit for 5'11" frame. The cut is flattering and modern. I plan to buy more!
