Girl's Guide on How to Turn Your Closet into One of Your Best Sources of Income ...

Make sure you do your research on lesser-known designer labels (I said lesser-known labels because people will obviously know the worth of a Chanel or Louis Vuitton). People in thrift stores tend not to pay attention to the labels. Take advantage of that, and do your research.

A lot of women don't shop at thrift stores because they think that they don't have good quality clothing. But you'd be surprised at what you could find in one. One girl once bought a fur coat for $4 and sold it for $1,000.

Look into investing in authentic vintage pieces one woman bought a vintage dress for 750 dollars at an auction and it's now worth thousands. But beware of the fakes, that's why it pays to do your research beforehand. If not, someone could scam you out of a pretty penny.

Make sure the items you're trying to sell are thoroughly cleaned and always read the instructions on the label before cleaning so you don't ruin the piece of clothing you're trying to sell.

Try to make your photos as professional as possible. Don't just take a blurry picture of shirt you trying to sell in your closet. Take photos where there's good lighting and position the item so it shows off its best features. Don't list the item if it's something you wouldn't buy.
