For those who have t-shirts that are far too big for them.
-An over-sized t-shirt. (Depending on your size, choose something that is at least two sizes too big.
-Needle and thread
-Sewing machine (if you own one)
-(Optional) Items to decorate the tunic with.
-An awl (Or a pen with a pointed cap)
-A seam ripper (Or your bare hands)
-An iron (Or some water and a ceramic flat iron)
Step 1: Making the Tunic
Take your shirt and lay it flat. If you do not like the design on the front of the shirt, turn it inside out now and then lay it flat.
Next, cut off the sleeves and toss them to the side. You'll be using those later.
After that, take your chalk and draw a straight line from the bottom part of the sleeve that you just cut off (where the armpit would be) to the space right next to the collar. Repeat for the other side. Cut following this line.
Now, put the shirt on inside out from how you want to wear it.. Pull the sides together under each arm. Experiment. How low do you want the armholes to go? I measured about two inches underneath my armpit, but you can choose to go as low or as high as you like.
After you measure everything out/make things symmetrical, pin from that point down to where you originally cut.
Sew that bit on both sides, turn the shirt right side out, and you're done!
Now for the bow..
