This detachable collar thing was super easy and fun to make! I used a shirt that I've had for a while but is too big on me so I never wear it. I cut the collar off the shirt making sure to cut along the hem so it wouldn't fray. Then I ironed it so it would have a nice crease. The shirt I was using had some pretty lace on it, so I cut the lace off and hot glued it to the collar! Done! The collar could be embellished in a ton of different ways. Sequins, beads, fabric paint, embroidery, buttons.. whatever you please!
