For this DIY you'll need a dress shirt, plyers, scissors, embellishments and a hot glue gun. I went to goodwill and found two cheap mens dress shirts, one white and one light denim. I found pyramid studs from hobby lobby, $3 for a pack of 20. I also used pearls, forever 21 earings and a pack of cheap crystals from micheals.
It's as easy as arranging the embellishments on the collar the way you want them and hotgluing them down. This looks easily dresses up a plain sweater, it adds that extra sparkle!
