I've found that a great solution to the "I have nothing to wear" complex is adding the right accessories. And the quickest and cheapest way to do that is to repurpose something I already have on hand.
Back around 2005 we were all wearing long beaded necklaces that hung down to our belly buttons. Nowadays, the cycle of accessory fashion has rotated back around to short and chunky. Trendy statement necklaces are layered and rest above the breastbone.
For this quickest of projects I repurposed those long necklaces from the previous decade into trendy statement necklaces. And here's the best part, I did it non-destructively and it took less than five minutes!
I started with a long beaded necklace, a roll of ribbon, and fabric scissors. Using fabric scissors on ribbon is important if you want to prevent fraying. Dull scissors will leave you with jagged cuts.
