Are the items being kept things you plan to sell in the future or things you are handpicking for your personal use/collection? Also, when is your moving timeframe? Is your house on the market or do you have a contract already? If your move will happen in 2-3 months, I would take all the better modern stuff - 90s through current - to a consignment shop, less the tiered early 90s prommy dresses. It is a fair amount of time for the stuff to sell, and you will get money in hand. What doesn't sell can be donated at the end. Of course, if the item is current and is a trendy brand, ebaying would work. Also, if you are an independent contractor, donation write offs help taxes and you could donate to one of those programs that provides interview suits to women reentered the workforce after being on welfare or being in rehab. There are also groups that take prom dresses and give them to girls whose families are lower income cannot afford it.
