I normally take a size 27 or 28 in Joe's and found that a size 29 worked best for me in these. The legs are very narrow and if you have muscular legs, sizing up may be your best option. I prefer the fit and price of these over Hoolihans. With a heel they make my legs look millions of miles long. Even sizing up, the overall look is very lean. They're also flattering with a flat heel as well.
