hello - well that's really frustrating when you can't find your size at good discounted price. I feel it all the time.
if you hem your jeans you must realize:
1) the value of the jeans will decrease dramatically. so make sure when you hem, you plan to keep jeans and not resale
2) sometimes 34L the behind the knees honeycomb will mis align from your knee.. also the bottom the pre stacking and wrinkles and often some minor details will be cut off from hemming
3) if you do decide to go w/ the hem, i believe there's 2 types of 'original' hem. I think ones called euro hem and the other is original hem. Euro hem is they literally cut off (or fold) the bottom of your jeans and keep the hem and stitching as is, then re attach it to shorter length. The original hem is cut the original stitching of the hem off, re attach the hem on shorter length but w/ new matching color stitches.
4) finally there's a cheap hem where they just cut off to your right length, and fold jeans up little bit then stitch it back together. Do not use this method.
