Another way to style an oversized shirt is to tuck it into your bottoms.
This style works best with a high-waisted bottom, as tucking the shirt in accentuates the waist.
It gives the illusion of a smaller waist and being slimmer without compromising on comfort.
For guys, there are different pants to pair the shirt with. For girls, you can pair the shirt with a skirt too!
This style can be done with short pants too! Other than pairing it with the usual denim shorts, a nice color pants work well too.
Pairing striped oversized tee with elastic band shorts work well too.
Fashion tip: If your bottoms is of a basic color, you can go for a color T-shirt or a striped one for a brighter image.
