2. Sewing method: Use a sewing machine or hand sewing to narrow the sides and shoulders of the T-shirt. Before sewing, it’s a good idea to turn the T-shirt inside out to make it easier to handle.
3. Cutting method: Use scissors to cut the sides and shoulders of the T-shirt, and then re-sew. Please note that this method may alter the original design and length of the T-shirt.
4. Manual shrinking: Wrap the T-shirt in a wet towel, and then heat it with an iron until the T-shirt becomes hot and begins to shrink. Then stretch the T-shirt with your hands to restore it to its original shape and let it dry.
