Most of my Consignors who do very well are the ones who provide either brand new clothing, never worn clothing, some with tags, and some w/o tags but in excellent condition. If you're consigning more on the "pre-loved" side but still great & worth a second life or vintage type of clothing, here's a great tip for you.
Get all the pertinent information on the item that you can. The ones who provide the most history on the items they consign do very well too. Customers like to know what's unique about the item, where it comes from and find that connection with it. In getting the full customer experience connection, I definitely love to give them as much information as possible.
For example, Is it handmade? Where did it come from? What precious stones or material is it made up of that makes it stand out from the rest? If it's Vintage, what year is it? Give me the full story. Stories are fascinating and when browsing, especially through a consignment or vintage boutique, they like to know a little bit of history. Customers are more picky these days and they want value in knowing they have purchased a unique find.
Another tip is being realistic with what you think an item is worth. Remember, we are a small boutique, in a small town of tourists and some locals that can easily buy brand new items from Macy's or Nordstrom. As a boutique we want to offer them something unique & different. People will pay for quality and/or uniqueness first and then realistic prices for average items second.
So be sure to get all the facts on your item before you consign. Ask yourself the questions above and give your item a full story. Be sure you are being reasonable about what you think it's worth, do some comparisons. And as usual, examine your items carefully. I'm sure you want to clear out your closet but keep in mind no one is going to buy something you would normally throw away. Make sure it has value. And most important, make sure your items are either washed or dry-cleaned with no stains, no loose threads, no holes, no loose hems & no loose beads before consigning.
Remember, if you want your money's worth, make sure it's worth it and ask yourself, if you were a customer, would you buy this?
