I'm usually a size 6 or 7, but in order to get a pair that fit, I had to order a size 11. I bought these for work, and my work shirt does have to be tucked in, so that accounts for part of the larger size. I suggest ordering a size or two up. So far they seem very durable and well fitting. The fabric doesn't stretch out too much during the day, so they retain their shape. The only downside is that there are no pockets on the front of the pants. It takes a little time to get used to having to put everything in your back pockets. Aside from the small sizing issue and lack of pockets, these pants are very nice and great for the price :)
