Selling Kids Clothes on Poshmark: A Busy Mom’s How-To Guide

Are you looking for a flexible side hustle you can do from the comfort of your own home? If so, then selling kids clothes on Poshmark is a legit gig for you. Hear me out…

When my sister schooled me on selling my piles of used kids clothes on Poshmark, I had my doubts. It sounded like a lot of extra work. As a busy mom of four, I didn’t need any extra work in my life.

After she walked me through the ins and outs of the platform, I gave it a try, keeping my expectations low.

Once I got the hang of it, I started earning money. In fact, I made over $1K in 8 months. It required minimal work, and it put money in my pocket, which I then used to replenish my kids’ wardrobes. After all, I was selling their used clothes, shoes, and accessories.

What is Poshmark?

Poshmark is a social commerce marketplace where people in the United States can buy and sell new or used clothing, shoes, and accessories. The company is headquartered in Redwood City, California.

Over the last few years, online fashion markets have proliferated. Kidizen. FB Marketplace. Tradesy. ThredUp.

You can sell your used kids clothes at any of the sites I listed above. I’ve had the best luck selling kids clothes on Poshmark! I’ve sold heaps of used goods. Clothes. Shoes. Backpacks. Accessories. Used snowsuits, rainboots, Halloween costumes, and pencil pouches, too.

What Do I Need in Order to Sell Clothes on Poshmark?

  • A Poshmark account. I do 100% of my selling from the Poshmark app on my iphone.
  • A printer, for printing shipping labels. We own a Samsung Laser Printer, and it works just fine. I print shipping labels on regular, old copy paper.
  • Boxes or polymailers to ship items. You can get free USPS supplies like boxes and envelopes delivered to your door if you order from the USPS website. I use a combination of free USPS supplies and polymailers.
  • Tape for shipping labels. You can order this from USPS or purchase from a store like Walmart or Target. I use Duck HD Clear Heavy Duty Packing Tape, purchased in bulk from Amazon.

How Do I Get Started Selling on Poshmark?

Create your Poshmark account.

It’s free. You’ll need to create a user name and provide a profile picture like you would for any other social media. You can add additional information like your gender, location, education, and a link to your website. Additionally, you can link your account to Pinterist, Tumblr, Twitter, Instagram, and YouTube.

Snap pictures of the items you want to sell.

  • After you have washed, dried, and pressed your item, it’s time to take photos. Poshmark allows you to take up to eight photos of an item at a time. I recommend you take eight!
  • Use natural lighting. Do not use filters.
  • Take photos in square mode so you do not have to crop them later.
  • Flat lays work well for Poshmark photos (see pic below). A flat lay is a photo of objects arranged on a flat surface, captured from directly above.

  • Take pictures of the front, back, tags, details, and any flaws.
  • You do NOT need a fancy camera. I take all my pictures with my iphone.

Write the title and description of your item.

  • Write a strong title description for your item. Does “Cute Girls Plaid Skirt” or “H&M Short, Pleated High Waist Skirt Size 8” sound better? Buyers are purchasing your items sight unseen. Entice them with details. Be specific and professional.
  • Write your product description. Provide the condition of the item (new, used, holes, snags, fading, etc.). Take measurements if applicable and list those too.

Set Your Price

  • Set your price. Poshmark will ask you for the original price of your item. Use your best estimate here. If you’re not sure how much to list your item for, do a search to see what similar items are going for on the site.
  • Do you want the brutal truth? If your item is used, you won’t get back what you paid for it. If your item is new, you still won’t get back what you paid for it. Period.
  • See my listing below. I bought these swim trunks for $18. My son didn’t like the fit of them (and I held on to them for too long and the return window passed). I priced these at $16. I’m wiling to sell them for $12. Maybe even $10. They’re new with tags. Never been worn.

  • I set my listing at 15-25% higher than the price I would be willing to sell at. Once someone “likes” your listing, you can make a private offer to him/her/them. Since you priced it higher at the start, you have some wiggle room to make offers and lower your price. There is an art to mastering this. You’ll have to play with your pricing a bit to see what works for you. Don’t price too high. Don’t price too low.
  • For all sales under $15, Poshmark takes a flat commission of $2.95.
  • For all sales over $15, Poshmark takes 20% of the sale. You keep 80%.
  • The buyer pays for shipping, but you can offer shipping discounts if you are so inclined.

List your item.

  • Open your app and click on the sell button at the bottom of the screen.
  • Select the photos you took of the items you wish to sell, crop, and pick a cover image for your closet.
  • Fill in the details (title, description, category, size, brand, and color).
  • Set your price.
  • Hit the Next button. Your listing will appear in your closet.
  • Sit back and wait for likes and offers.

What to do once someone has purchased your item.

  • Poshmark emails a shipping label to you. Print it out.
  • Neatly fold and place your item in box or mailer.
  • Affix label to the front of your package.
  • Put package in your home mailbox or drop off at your local USPS. Usually, I leave my outgoing packages in my mailbox unless they are very large or heavy.
  • Click on the Sales button in your app and check the box to indicate that you have shipped the item.
  • You get paid once the buyer receives and accepts the item.

Miscellaneous Tips for Selling Kids Clothes on Poshmark

Be responsive! Buyers will ask questions. Be prepared to answer them if you want to make a sale. Once a buyer accepts a purchase, they rate you on the site (1-5 ⭐️s).

You can sell items in a “bundle.” Obviously, if you’re listing a bundle of three shirts, they should all be in the same size. Buyers love bundles, especially when they’re shopping for their children.

Below you’ll see a screenshot of one of my bundles. The listing is for three boys athletic shirts size medium (10-12) in EUC (excellent used condition).

Note that in the item description I listed the shirts as #1-3 and provided extra details about each individual shirt.

I set up a Poshmark space in my house. My supplies and listed items go in this space. It’s all organized for when I make a sale.
