I assume you are talking about the Joeys, where the stitching goes diagonally across the bottom of thefront and back of the leg?
On some joeys the leg stitching starts higher, or doesnt slant as much, so it would also look nice when hemmed. I suggest when trying them on, you fold the bottom of them in until they are your length and then decide if you like it that way. Or, if you are planning to buy them online, what i do is look at the inseam length and just eyeball it
