If your low on cash, it's easier to revamp an outfit with accessories than to buy new clothes.   Accessorizing can add excitement and variety to your look. 
Accessories like scarves, jewelry, belts, hosiery, hats, jackets, shoes,  camis and t-shirts  can make a simple pants suit look exquisite even with multiple looks.
A white blouse with a silk print scarf over your shoulders can create a sophisticated look. Seek unusual jewelry like artisan crafted or costume pieces.
 By adding a few  bracelets  to a sleeveless t-shirt can add a bit of interest.
Do you find yourself always wearing the same jeans and t-shirt?  Pair the jeans & t-shirt with a leather blazer or a button down cardigan sweater.
 Take a simple black dress and add a jacket for serious business look.
Transform the same black dress with a beaded clutch purse and stilettos for a evening on the town.
Multiple layered looks can change looks.  Try wearing a cami under a long sleeve shirt for a different look.  Have fun with your wardrobe and instead
of buying something new incorporate the accessories that are already in your wardrobe.
