That fitted black shirt you want to buy is sold out in your size. If you purchase the next size up, it won't have the fitted look on you. Instead of sulking, go ahead and buy that black shirt in the next size up. You can easily shrink it in the wash and retain its vivid black color with the proper care.
Things You'll Need
Soak the black shirt in a solution of 2/3 cup vinegar to 1 gallon of water for 15 minutes. This will help keep the color from fading in the wash.
Place the black shirt in the washing machine inside out.
Add color-safe detergent that will prevent the black color from fading.
Set the washing machine for a hot washing cycle. The hot water will cause the fabric to contract and shrink. T-shirts that are 100 percent cotton will be the most affected and will shrink the easiest. Other types of fabric such as polyester and cotton blends will shrink less.
Place the shirt in the dryer on the highest heat possible and leave in the dryer until it cools.
Try the shirt on and see if it fits better. It if is a little too tight, try ironing it to stretch out the material a bit.
You may have to repeat the process a time or two for fabrics that do not easily shrink such as polyester, rayon and silk.
Do not wash the shirt with any other clothes unless you want to shrink those as well.
