These pants run very small, particularly in the waist. I generally wear a size 2 - 4 which translates into a XS or S. I tried both the size 2 and size 4 and neither fit. After finding that the size 2 didn't fit I referred to the Mountain Hardware sizing chart and ordered the size 4. According to this chart I would wear a size 2 or 4. The size chart may be accurate for other MH items but it's not accurate for determining your size in the Ellinor Capri Pant. I gave up on trying to get a fit in these pants so my rating doesn't reflect how I feel about the pants themselves but rather the poor measurement to size concordance.
