This is a good start! Surely if you keep working you'll get to make great games! Keep going :)

This was made in 2017...let that sync in

The game should have a way to properly put the clothes onto the character, and the player shouldn’t be able to stack multiple sweatshirts onto the character as well.

You don’t actually have to drag the clothes onto the character. Simply clicking on the clothes should work.

Try adding more pants/skirts and perhaps shoes and more items.
