Here are a few of the many t-shirts I have hidden in my closet. Since my current style largely involves the use of outerwear, I went ahead and styled these tees with some baggy jackets and came up with three grungy outfits. I actually cut the yellow tee in the middle into a crop top because y'all know how much I love my high waisted things. If you have a collection of graphic tees or loose t-shirts, pair them up with jackets or cut them out to your liking.
Here's another set of what I used to hoard back in my middle school/early high school days - long sleeves. I have a vast collection of thermals, most of which I don't really use anymore, but there are so many new ways to style them. For the first plain white top, I just folded the sleeves and added a form-fitting collared vest for a casual business look. I love the look of long sleeves and skirts, so I paired the mustard yellow top with a basic skater skirt for a girly fall outfit. I also threw on a fringe scarf to spice it up a bit. The last top is actually a sleepwear, but you can always style one for casual or lazy days. I paired it with high-waisted cotton shorts and a striped oversized vest for a very comfortable look.
If you don't like the fit of your old jeans, cut them into your desired length. I snipped a bunch of my straight-cut jeans into shorts and added distressed details. This will save you a lot of money because most daisy dukes cost just as much as jeans, which I'll never understand.
