Going off to college, you bring your whole wardrobe along and maybe wear a third of it, all while the rest of it collects dust. If this pertains to you, then you should sell the things that you no longer wear and stop being a pack rat.

If you are feeling generous, take your clothes to Goodwill or the Salvation Army, but you won't make a profit off that. If you want to make money by selling your trendy clothing, download the apps Grailed and Depop.

These are two apps that are very simple to use. Depop has a layout similar to Instagram, and Grailed works just like a typical clothing website. All you have to do is go through your closet, find something you no longer wear (but make sure the item is still in decent condition so that someone else can get some use out of it) take a few pictures, and post it to the app. You can sell your products for however much you desire. There is also an option available for people to offer a price for your item as well.
