I am 5 foot 7 3/4 inches tall to be perfectly exact. Last time I weighed myself I was about 155 pounds. I have a slim waist and thick bottom and so I decided to order a Medium. I bought this pants suit for a wedding rehearsal. The material is a bit sheer in the light - youll need to wear panty hose or some kind of shorts underneath. Its very casual and SUPER long. I pulled it off with some heels but Ill probably get it hemmed a little and I don't usually have that problem. But I was able to dress it up and got a lot of compliments on it. And for price I really cant be mad. It was a steal.
