how long should jeans::Common sense: always go for the longer pair, so you can always have them cut to length afterwards.
Too short is too short is too short.
This will allow for that bit of shrinkage.
The sitting measurement is not indicative as the amount of rise will depend on type of fabric and cut of the jeans.
Your pair of jeans will widen due to the fabric stretching, this usually will just take an hour.
Some folks will let them hang on their hips, adding some length, other will hoist them back up with a belt, loosing length, what do you do?
Shrinkage: the darker a fabric is, the more shrinkage you have to generally allow for.
Even the lightest of jeans usually start their life very dark but have been treated extensively, this will often decrease durability but will also reduce shrinkage.
A pair of jeans is generally worn a small inch longer than suit pants, which only have to rest on your shoe, with a little bend at the front.
A little tip: very often a longer pair will be a bit bigger in the waist.
You can try the longer pair in a size smaller.
Try a different color or fabric, lenghts very per washing, even try more of the same size!
