There's a number sitting in your closet right now that you don't know.
Not what you paid. What it's worth today — on the resale market, to buyers who are actively looking for exactly what you own.
For most people, that number is surprisingly large. The average American household has an estimated $1,000 to $2,500 in unworn clothing. A meaningful portion of that has resale value that's gone completely untracked.
Why most people underestimate their closet's value
A few things happen consistently:
You remember what you paid, not what it's worth now. The jacket you bought for $80 in 2021 might resell for $120 today because the brand discontinued it. Or it might resell for $25. Without checking, you have no idea.
Resale value is category-specific and volatile. Lululemon Align leggings hold value almost like denim. A fast-fashion dress loses 80% of its value the day it leaves the store. Vintage Nike from the 90s has appreciated 300% in some colorways. These markets move constantly.
Out-of-season items get forgotten. The winter coat buried in the back of your closet isn't on your radar in July. But someone is searching for it right now on eBay, and the comps are higher than you'd expect.
You don't know what you have. Most people can't name everything they own without physically going through it. If you don't know it's there, you can't know it has value.
The items most likely to be undervalued
Based on what resale markets consistently show:
Athletic wear from premium brands — Lululemon, Athleta, Vuori. These hold 40–70% of retail value in good condition. NWT pieces sometimes fetch over retail.
Vintage denim — Levi's 501s, especially made in USA, regularly sell for $80–$200+ depending on wash, size, and condition.
Sneakers, especially Nike and New Balance — Even general release colorways from a few years ago sometimes appreciate. Rarer drops can be worth multiples of retail.
Contemporary women's brands — Free People, Anthropologie, Reformation. Buyers on Poshmark pay well for these, especially in extended sizes which are undersupplied in resale.
Designer accessories — Bags, belts, scarves from brands like Coach, Kate Spade, or even Fossil hold value better than most clothing.
NWT anything — New with tags is a significant premium driver across every category.
How to actually find out
The manual way: search Poshmark, eBay, and Depop for each item. Filter by sold listings. Do this for everything you own that you haven't worn in 12 months.
If you have 50 items, that's a few hours of research. If you have 200 items, it's a weekend project.
The automated way: Cove connects to your email, reads your purchase receipts, and builds your complete inventory automatically. Then it pulls real-time resale comps for everything you own, surfaces the items with the most value, and flags when something spikes so you don't miss the window.
The goal isn't to turn everyone into a full-time reseller. It's to make sure you're not unknowingly sitting on a $400 pair of sneakers while you're paying your credit card minimum.
A simple audit to start
Even without any tools, you can do a rough triage right now:
- Pull out every item you haven't worn in the last 12 months
- Separate NWT from worn
- For anything over $50 at retail, do a quick sold comp check on Poshmark or eBay
- Make a list of anything showing comps above $30
That list is your resale opportunity. Even converting half of it to cash has a real impact.
The honest reality is that most of us are carrying value in our closets that we've written off. Some of it is genuinely worth nothing on the resale market. But some of it — more than most people expect — is an asset waiting to be converted.
The first step is just knowing what you have.
