Want a cheap way to make a 99cent T-shirt seem fitted?
All you need is a scissors and a cheap T-shirt, and you can show off!
Step 1: Fold your shirts in half
Fold both of them in half.
Step 2: Match up the t-shirts
Carefully match up the tops of the sleeves and the centerlines, keeping them individually folded and with the smaller one placed on top of the other.
Step 3: Cut here
Start cutting the shirt in strips up to the point where the other shirt starts.
Feel free to change the width of the strips, keeping in mind that the thicker the strip, the larger might be the hole where you'll be knotting.
The pattern I used here makes for a "kimono" styled open armpit.
You might want to experiment.
