Are you selling these on ebay? If so, Ebay has tips for creating better photos
Here’s an ebay clothes selling for dummies article.
This is a good starter for clothing terms to use when selling online.
I personally have an ebay store. My best tips for you to sell your items quickly & present them well:
-Use a white or light colored paper or sheet back drop.
-Use pure white lights aimed at the item
-For clothing use a mannequin or simply hang the item on the back of a (clean) door or put a hook on a (clean) wall to display.
-Measure the item and put the measurements in your listing
-Whenever possible give more details (Only worn twice, fits loose, fits like a size larger)
On a mannequin or on a model (no face shots) does sell items quicker…either that or find a stock photo of your item online.
