T-shirts in solid colors go a long way in making outfits! Of course you'll want at least one in black, white and gray, but also add pretty colors to the mix. Basic tees pair easily with all your other basics and non-basics. Have long sleeve T-shirts for the fall and winter and short sleeve for the spring and summer! Solid T-shirts are really useful not only because they can be worn with many other items, but also because of their versatility for different occasions! Depending on what you wear with them and how you accessorize, you can take a tee to dinner, work, lunch or weekend.
