If you're into the style of skinny jeans, or feel you have a body on which skinny jeans look attractive, you may enjoy wearing this style of garment. But occasionally, you may end up with a pair of jeans that are a little too baggy for your taste. When this is the case, you can shrink them with the washer and dryer and with some well-placed sewing.
Place the jeans in the washing machine and turn on a hot-water cycle. Run the jeans through one cycle of the machine.
Remove the jeans from the washing machine and put them in the dryer on a hot cycle. Once the cycle finishes, remove the jeans and try them on. They should be noticeably tighter, and perhaps you don't need to alter them any further. If they're not quite as tight as you'd like them to be, run them through another washing machine and dryer cycle to shrink them a little more.
Put the jeans on and pull at the denim to see how much tighter you wish them to be. Remove the jeans.
Turn the pair of jeans inside and, with a thread that matches either the colour of the denim or the colour of the thread used in the jeans, sew a line along the inseam of each leg, adjacent to the pre-existing stitching. The line should slightly pull the denim together, serving to tighten the leg along its entire length.
Sew as high up to the crotch of the jeans as is required. If the jeans are already tight enough around the crotch, you may wish to sew only to the mid-thigh. Put the jeans on to see if they're tight enough.
If you're not comfortable with using a sewing machine, repeated hot cycles in the washer and dryer will continue to shrink your jeans.
