i agree with the opinions above. if you're paying a lot for expensive jeans, it's definately worth it to go the extra mile and get them hemmed, and hemmed correctly. personally, i think the worst thing you can do to a pair of nice jeans is to hem them without originals, or drag them along, tearing up the fabric. original hemming can be expensive, but in the long run, the jeans are costing upwards of $150 so what's another $20 or so?
diesel makes some jeans with an inseam of 30", which usually comes out closer to a 31"-31.5". paige, seven for all mankind, and joe's all have 'petite' fits, though the inseam still comes out pretty long, say, 31"-32", which is still shorter than the standard of 34". skinny jeans are easier to find, try the siwy hannah skinny crop, which is ankle length, or the j brand 910 fit, again, also ankle length. also, i have a pair of miss sixty skinnies, and a pair of rich & skinny skinnies, both with inseams around 30" unaltered.
