Sweatshirts can be cut to sleeveless sweatshirts and used as sleeveless undershirts. Done right, they can also be used as sleeveless shirts on colder days. This article will look at how to make sleeveless undershirts from sweatshirts that are neat enough to use as sleeveless shirts themselves.
There are two reasons sweatshirts are less desirable than T-shirts as cutoff sleeveless shirts. First, the shape of the sweatshirt does not lend itself well to becoming a sleeveless shirt, and second, the material makes for a shirt that is too hot to wear on days when sleeveless shirts are worn. Because the shape of the shirt can be amended to make a sleeveless shirt out of a sweatshirt that fits comfortably, sleeveless sweatshirts are a viable option for use both as a sleeveless winter undershirt and a sleeveless shirt for those who can’t stand sleeves on cooler days.
Measure the sweatshirt against a comfortable but good fitting T-shirt. If the sweatshirt is over an inch wider, it will need to be modified. If it is comparable in size, simply cut the sleeves off. The seam can be left on or removed. Leaving the sleeve on makes a shallower arm hole; cutting it off allows greater comfort and better appearance but risks having the armhole too deep.
For larger sweatshirts, cut the excess material off of the sides, past the sleeve and stopping at the base of the T-shirt sleeve. From there, angle into the sweatshirt to follow the curve of the T-shirt seam. Turn the sweatshirt inside out and sew the sides together. It is important to use an actual T-shirt as a guide to avoid making the shirt too tight. Try on the sweatshirt and make any necessary trimming. Usually, the arm holes may need to be rounded at the base and the shoulders trimmed back if too wide. Sweatshirt cloth does not fray so hemming is not necessary. The cloth does not curl over, so it may need to be trimmed back whereas a T-shirt would curl back. Save the sleeves for other useful crafts.
You now have a sleeveless sweatshirt that is perfect for use as an undershirt. Sleeveless sweatshirts make great winter pajama tops and can also be used as sleeveless shirts by those who don’t like sleeves on cooler days.
