I Ordered a Large it fit me well I am 5'5 170 mostly hips, usually wear a medium but I recommend size up... The pants have plenty space, except for waist does not stretch, advice don't buy if you have large waist area. Good material dark, but cotton light and soft. Great for those hot summer days you must go to work, the backside of the vest show half your back, you can throw on a blazer and it will work and take it off for happy hour 😀
