Skinny Jeans cost so much in the stores, why spend $$$ when you can make them yourself :P
I go to thirft stores/good will stores and buy jeans then just sew them up myself!
Turn your jeans inside out then put them on.

Sit down, make sure your legs are flat and that the pants legs are straightened out.
Draw a line from the bottom of the pants leg to the thigh (I usually just go all the way up to the crotch area). What your doing is your drawing the line your going to sew on, so make sure it isnâ€™t too close too your leg (so that its not too tight) or too far (so that itâ€˜s not too loose). Make sure you can get your foot in and out of the pants hole too.

It should look like something like this after youâ€˜ve draw the line (just pretend the jeans in the pic are inside out :p)
Once youâ€™ve got your lines drawn, you can start sewing along them. One leg first, then the other.
If your sewing by hand be sure to check (try them on) every now and then to see if they fit okay. If they donâ€™t youâ€™ll have to redraw your line and possibly start over.
When you finish sewing up both pants legs try them on.
If they fit then you can take some scissors and cut off the excess jeans.
After cutting them: To keep the parts thats left from fraying, you can stich them up. (thanks tama_sempai!)
Turn them back out. They should look something like this:
YAY you made some skinny jeans! Now wear them!
