When you're paying top dollar for kids' clothes, you want a few bucks back for them.
"Kids go through seven sizes in the first two years," Minneapolis mom Dori Graff said. "So as a parent, you're always buying and you're always needing to get rid of things."
That's why Graff and her friend Mary Fallon created the iPhone app Itizen for parents to buy, sell and trade clothes for their little ones. Itizen is part eBay, part Facebook: The app combines an online marketplace with the ability to "follow" other users whose offerings match your needs and taste.
Here's how it works: You snap a picture of the onesie your toddler has outgrown. You name a price and a shipping cost, and then you add some descriptors that help shoppers find you, such as size, gender and brand. Then you post the listing to your profile.
Itizen is available by invitation only, but those interested can visit www.itizen.com to request an invite. The app has about 3,000 users so far.
Clothes are "the thing that floods every mom's closet space," said Joan Park, a New York City mom who uses the app. "It's really great because my daughter … there's no way she can wear all this, and it doesn't wear out. So I would love to let someone else get the life of the clothes, and then also get something back so I can invest in expanding her wardrobe for later seasons."
Park said the app attracts higher-quality items than you might find at a secondhand store. She gives baby clothes to other moms and to her church, but she saves pricier outfits for Itizen.
"It's a separate pile, the level-A stuff," she said. "It's worth my time to put it on the Web, and people will be attracted to it."
