Easy peter pan collar and bow to vintage-up an old shirt!
1
First get the shirt you want to sew, it doesnt even have to be black. I got mine from Forever21 for like 4$.
2
Now get the fabric you want to use
3
Cut out collars using patterns or by folding fabric and cutting by hand so that they come out exactly the same.
4
Now get different(or same) fabric and make a bow out of it. I made mine by cutting out a strip and hemming it and then cutting a shorter strip and folding it around the other strip
5
Hem your stuff and sew it onto the top of the shirt and wa-la!
