For reference, I'm 5'3" and around 115 lbs

I bought this skirt in the medium/large size because of what I read from the other reviews, but unfortunately it's too large. I'm not going to return it though, just take it in a little at the waist band. I'm not sure that the small/petite size would fit though, as I don't know what 'petite' means, maybe a child's size.

Either way, I would recommend this product. I got it for a great price and it will be super easy and fast to take in.
