Q&A for How to Shrink Clothes in the Wash

The hotter the water, the more it will shrink. The change shouldn't be enormous though.

Nylon clothing typically does not shrink, but will stretch out over time if it has any spandex rubber woven in. Nylon itself may melt in hot dryer. Best bet is to have the pants altered by a seamstress.

Everything will shrink. The size of the print may become scrunched, though, so be careful.

The first method will work fine. I have leggings that are cotton and spandex and it worked for me.

It depends on the material you're washing. Detergent will work on most materials, but softener could work as an alternative.

Some fabrics are distinguishable, like silk, which feels smooth and slippery. If the fabric is not distinct, you may need to try and find the shirt online or guess by comparing it to your other shirts.

You cant; cotton shrinks, viscose doesn't. Cotton shrinks at very high temperatures, and viscose will only crush.

Don't expect there to be a big difference at first. You'll have to keep trying until it gets to your desired size.

Wash it in cold water and then dry it in the dryer. I've done it before, and it worked fine.

The color fades as you wash it. Heat will also wash it out. You can't see a difference if you don't put a whitening solution in when washing.
