Welcome Sellers!

Thank you for your interest in the Cossitt School Children’s Clothing Consignment Sale. This community tradition has thrived for over 40 years, benefiting the students and teachers of Cossitt Elementary School.

The Deal: Sellers keep 60% of their sales, and the Cossitt Parent Teacher Council earns 40%. All unsold items are donated to local charities.

  • The Cossitt Children’s Clothing Consignment Sale is a twice-yearly children’s consignment sale and 40+ year community tradition. Year after year, shoppers come from far and wide for great deals on gently used, high-quality children’s clothing, shoes, and books. Our sellers keep 60% of the sale price while the Cossitt Parent Teacher Council earns 40%. Proceeds benefit the students and teachers of Cossitt School, and donations of unsold items help children throughout the area.

  • You can sell gently used children’s clothing, shoes, and books. Be sure to check our list of Acceptable Items below. At our Fall Sale (September), we sell fall and winter clothing, and at our Spring Sale (March), we sell spring and summer clothing. We don’t sell toys at our sale.

  • The week before each sale, we have a Technical Assistance Night for sellers to print tags, pick up cardstock paper, use our paper cutter, view samples of tagged items, and ask questions of our friendly volunteers–all at absolutely no charge. Information below:

Preparation & Drop-Off

Quality Standards

Look over your items carefully for stains, holes, worn knees, missing buttons, or broken zippers. (If any of these issues can’t be fixed, you can donate these items to Go Green Greater La Grange at their textile take-back event on Sunday, March 15th. )

We maintain high standards to ensure a great sale. Items will be rejected for:

  • Stains, holes, or excessive wear.

  • Odors (smoke/pets).

  • Wrong Season: We only accept Fall/Winter items in September and Spring/Summer items in March.

  • We will also reject items with tags from previous sales or tags that have been written on or altered in any way.

How to Prep

  • Clothing: Hang with the hook facing left (like a question mark ?).

  • Pants: Pin to the top of the hanger on both sides.

  • Shoes: Zip-tie together; tape tag to the bottom of the sole.

  • Books: Group sets with rubber bands; tape tag to the cover.

Where does the tag go?

  • On clothing, the tag goes on the upper-right side of the item (the wearer’s left shoulder or hip).

  • On shoes, tape the tag to the bottom of one sole or secure it inside the shoe.

  • On books, tape the tag to the front or back and cover it with regular adhesive tape.

  • On large items, tape the tag securely with clear packing tape. It’s OK to cover the whole tag with tape.

My items are tagged. When can I drop off my things?

  2. Transport items to the school in laundry baskets, bags, or boxes.

  3. Required: Bring a self-addressed, stamped envelope with your seller number on the bottom corner. We use this to mail your check!

Quick Pricing Tips

  • Bundle for Value: If you have basic items (like plain white tees), pin 2 or 3 together and price the bundle for $3.

  • Condition is Key: If an item is "like new" with tags, you can lean toward the higher end of the range. If it shows any wash-wear, stick to $1 or $2.

  • The "Would I Buy It?" Test: Ask yourself if you would pay that price for the item in its current condition.
