Selling second-hand women's clothes
Basically, selling second hand women's clothes uses the same principles as selling 2nd hand clothes : mens and kids.
Make sure you have checked the garment to see if there are any faults, marks, tears etc. Also, make sure its freshly washed. If there are any faults make sure you list them : being honest may mean you get a lower price but it also means you wont get any problems after the sale with disappointed buyers and requests for refunds or negative feedback.
For women's clothes however, I would suggest you keep in mind that you may not get the number of bidders you'd get for kids clothes so if you can't part with something for less than $10, then make that your starting bid price.
Its always a great idea if you have a number of items that are the same size, try to list them around the same time so potential bidders can look at your other items for sale and combine them with postage discounts (always offer postage discounts - it makes good sense).
