Lucky Sweater is a circular closet trading app.
On Tuesdays, we swap!
We’re a secondhand community platform for swapping out items you don't use anymore for new faves, for free. Just pay for shipping to swap your item. Trade your way to a closet that shifts with your identity, size, and style.
List items in your closet to trade, sell, or gift, share looks for style inspiration and outfit tracking, and have fun getting dressed alongside our growing community of secondhand style enthusiasts.
How it works:
- Join our community groups: Slow Fashion, Curated Thrift, Me Made, Vintage, Outdoor Gear, Kids Slow Fashion, and Gender Swap.
- Help others know what you're looking for by adding your "in search of"s (ISOs) to your profile, including your unicorn ISO.
- List items in your closet to trade, sell, or gift to other members of the community.
- Every Tuesday there’s a new Swap Drop, with more chances to find your dream ISO or fill a crucial closet gap
- Save or Super Save the items in circulation that you love.
- Start trading when people save items in your closet — that’s a Save Match!
- Get ready to send your traded item to its new life with easy in-app shipping. We encourage reusing packing materials, and adding a thank you note when life allows.
- Sustainers get access to all community groups, 5 Super Saves per week, 3-hour early access to the Weekly Swap Drop, item protection on all trades shipped in-app, and more perks brewing!
Who we are:
Lucky Sweater is a community-first, trade-forward, buy-curious experimental space for exploring fashion as a tool of creative self-expression, and we’d love to share closets.
Lucky Sweater is for:
People who find meaning in getting dressed.
Humans on a quest to curate an intentional closet.
Folks who value quality and craft over quantity.
Secondhand style enthusiasts looking to build community with others on the hunt for THAT. PERFECT. THING.
Makers, menders, up-cyclers, thrifters, closet-curators, capsule collection-devotees, and everyone in between.
Those who want their beloved but no longer worn items to be treasured by someone who *gets it*
Community-minded humans who believe in the circular economy, kind communication, and keeping well-made clothes out of the landfill — joyfully.
Lucky Sweater might not be for you if:
You’re mostly looking to sell stuff quickly.
You’re here to “flip” items or turn a profit.
You’ve never felt emotionally connected to an article of clothing.
You don’t want to respectfully engage with others or follow group guidelines.
And that’s okay! We’re not for everyone. But if you're someone who lights up at the idea of trading a beloved item that’s no longer serving you to someone who’ll truly appreciate it and give it new life? Welcome, you’ve found your people.
Recent App Updates:
We just launched Search by YOUR Measurements for our Sustainers — Because sizes are made up and meaningless! Brought to you by the LS community, who takes care to add at least 3 accurate measurements to all 20K+ items available on the app.
Our newest group, Curated Thrift, just launched! Picture a curated secondhand store, on your phone. This group keeps trades flexible with a fluid brand list, ensuring more of our favorite pieces stay in circulation and out of landfills.
Buy & Sell across all groups (even ones you’re not in) during our end of the month Buy & Sell Days!
This app has saved my wallet and refreshed my style

I love the community that is on Lucky Sweater! Thanks to this app and the community of people who are on it, I’ve refreshed my closet on a very very limited budget, and I even joined a no buy/low buy challenge that has saved my wallet (and my savings) big time. There are different types of communities on here and more are launching so you can trade not only slow fashion brands but handmade/me-made items and materials, too. Trading across the groups is very fun, and it increases the ability for people to acquire slow fashion items that they may otherwise not have the means to access (it has certainly been true for me.) The founders also respond directly to questions and comments regularly, and it really shows that they care about what they are building.
Circular Economy + Community Charm

Lucky Sweater is my lucky charm! This is not just a slow fashion trading app—it’s a community of thoughtful, diverse, inclusive people making connections and sharing advice about how we treat and think about our closets (and the planet). Come for swapping out and refreshing your closet. Stay for the kindness, encouragement, and engaged community that is LS. Don’t have a lot of slow fashion pieces or have no idea what slow fashion even is? This space is still for you! See “gifting” as a category! And look through the discussion threads on how to get started on keeping a more sustainable closet. The amazing women behind LS actively listen to community feedback, which means the space/app just gets better and better all the time. I cannot wait to see what trading space LS branches out to next.
My favorite social media

I’ve been on Lucky Sweater for two years now (with a paid subscriber for most of that time). Thanks to the swapping portion I’ve reduced my total closet by half, but what is left is things I love and actually wear! Thanks to the app as a whole (messaging and trading with people, posting and interacting with fit pics, posting and interacting with discussion questions) I’ve found community and friends and inspiration, new brands to support or search for secondhand, and a renewed love of gifting. I especially love the support of artists, with the ability to sell your own art throughout the month (other types of items can only be sold one weekend a month).
Jfc I love this app

Hands down my favorite app on my phone. Truly the best internet space I’ve ever been a part of. Swapping clothes? Mending advice? OOTD pics? Fun style challenges and prompts? Dressing like birds for the hell of it? We have it all! Easily the best monthly subscription I’ve ever had in the history of my life into eternity. On what other app can you find a community mode helpful, thoughtful, intentional, uplifting, and kind? The answer is: you can’t. Because it’s happening right here, every day. It’s so beautiful! And FUN! Lucky Sweater not only revived my wardrobe, but also my heart. May this app live forever and ever amen.
