Having the ability to shrink your trousers a size is the difference between buying new trousers and recycling the ones you have. When you lose weight it is easy to find yourself with clothes that are a size too big. If you shrink your trousers a size you will save money. Also, you will not have to take trousers back to the store when you buy a pair without trying them on. Instead you can shrink them a size and save yourself a trip.
Put your jeans on.
Fill your tub with water that is as hot as you can stand it.
Get in the tub with your jeans on. Sit in the tub for about 30 minutes.
Drain the tub.
Stand up in the tub until your jeans are not dripping anymore.
Let your jeans dry on your body and continue to wear them the course of the day. The jeans will conform to your body.
Put your cotton trousers by themselves in the washer. Add detergent.
Wash them on the hottest setting available.
Put your cotton trousers in the dryer when they are done washing. Put the dryer on the hottest setting. Keep your trousers in the dryer for at least 30 minutes.
Turn your shower on with only the hot water running.
Hang your wool trousers up on the shower curtain bar. Keep them far enough away that they do not get waterlogged but close enough to benefit from the hot steam. The hot steam will shrink the trousers. Leave them there for 30 minutes.
Take your trousers from the bathroom and hang them up where they can air dry.
Do not walk out onto carpets when your jeans are still dripping. The dye will stain your carpeting. Do not go biking in wet jeans because it makes the jeans' knees huge.
