without spending any money....
Make your current clothing and accessories work double duty for you...hacks from the curate style files.
1. Long Necklace: make it into a short necklace or into a stacked bracelet. You can just wrap it round your neck twice and create a layered look , or for more interest put the necklace behind your neck, and pull one end through -- you can now create a lariat. To "fill the space" in a v-neck or button down, put a knot in the necklace. Last but not least, wrap it around your wrist to create a bracelet.
2. Button Up Shirt: wear as expected, tucked and buttoned, or put up the back collar and leave it untucked. You can create a "jacket" by tying knots in both ends of the shirt, or wear as a crop over a dress or tank by tying both ends together up high. Now sleeves -- don't just roll them twice -- try creating a short sleeve shirt or a french cuff.
3. Belts: Not just for denim -- use if over a longer shirt or maxi to create a waist. Add interest by putting the buckle in the back or wearing a belt made of unexpected material (like that gift ribbon you love!) And that "self belt" from a dress -- use it as a headband or thread it through the loops of your favorite denim.
