It really doesn't get any easier than making this simple t-shirt dress pattern. The best part is that half of the pattern drafting is already done for us. In this tutorial, I show you how to convert our basic t-shirt / tank top bodice pattern into a t-shirt dress. (We recommend that you do that tutorial before attempting this one.) In a few simple steps, you can have a classic tshirt dress pattern that's comfortable and versatile. You can also add our other tshirt detail ideas like adding a yoke or sleeves. For assembly, you would still follow the steps shown in our tank top assembly tutorial. The steps are exactly the same, the pattern is just a little longer.
