How to sell used children's clothing in Colombia: sizes, bundles, and trust

Children grow at the speed of light. One day you buy them that beautiful onesie, and a couple of months later, it doesn't fit anymore. As a result, Colombian families' closets end up full of practically new children's clothing. Selling these outfits is not only an excellent way to recover some money, but also to help other parents and give the garments a second life.

If we look at market data, the opportunity is huge: according to active ads on Colombia Move (July 2026), there are currently 0 ads in the children's clothing category, which means that the demand from buyers looking for these types of items completely outweighs the supply. It is the ideal time to clear out that closet and generate extra income!

The sizing system in Colombia (Babies and Children)

One of the biggest challenges when buying or selling children's clothing online is getting the size right. In Colombia, sizes are divided into two main stages: babies and older children.

For babies, the standard for recognized brands like Baby Fresh or EPK is measured in months: 0-3m, 3-6m, 6-9m, 9-12m, 12-18m, 18-24m, and 24-36m. For older children, numbers based on approximate age are used (Size 4, 6, 8, 10, 12, 14, 16). However, since every child grows at their own pace, it is essential to know the height equivalent in centimeters.

Children's Size (Colombia)	Average Height
Size 4	~ 104 cm
Size 6	~ 116 cm
Size 8	~ 128 cm
Size 10	~ 140 cm

A practical tip: When you post your ad, don't just put "Size 6". Include the height in centimeters in the garment description. This drastically reduces buyer doubts and speeds up the sale.

How to prepare clothes for sale (Hygiene and Quality Control)

Children's clothing in excellent condition and well-presented has a high turnover, but it requires patience to find the ideal buyer. Before taking any photos, perform a strict quality control at home:

• Wash and iron: A wrinkled garment or one with a musty smell loses all its visual appeal. The first impression is what sells.
• Check the details: Look for food stains, wear on the knees, missing buttons, or damaged zippers. Be completely honest; if the garment has a small flaw, mention it in the description.
• Create lots (bundles): For basic items like bodysuits, everyday t-shirts, or pajamas, it is much more efficient to sell in "lots" of the same size. Instead of selling 5 loose t-shirts, offer the complete lot at an attractive price. More expensive items, such as winter jackets or party dresses, sell better individually.

Photos that build trust without filters

The success of your sale depends largely on the photos. You don't need a professional camera, just your cell phone camera and good natural light.

Take the photos during the day, preferably near a window. Avoid using the flash, as it alters the true colors of the fabric and makes the clothes look worn. Place the garments on a flat, neutral surface, such as a clean wooden table or a well-stretched white sheet.

Make sure to take a close-up photo of the label where the size and brand are clearly visible. Also, if the pants have slight wear on the hem, take a photo of that detail. Total transparency prevents returns and protects your reputation as a seller.

Where to sell: Comparison of options in Colombia

There are several platforms for selling used children's clothing in Colombia, but the costs and business models vary quite a bit, which directly impacts your final profit.

On one hand, GoTrendier is one of the best-known fashion platforms in the country. However, you must keep their fees in mind: according to their cost list consulted on July 9, 2026, they charge a commission of 9.99% + $3,999 COP (plus VAT) per sale made to the seller. On the other hand, Petit Loop, according to their site consulted on July 9, 2026, operates under a circular economy model where you can exchange children's clothing using a virtual currency called "loops" or, alternatively, receive money.

If you prefer not to give up part of your profit and are looking for a more direct deal, Colombia Move allows you to post 100% for free and without hidden commissions.

Safe delivery without disputes

Once you find a buyer, the delivery logistics must be safe for both parties. For local deliveries in your same city, agree to meet in a public, well-lit, and busy place, such as a shopping mall food court.

If you are going to make a national shipment through recognized carriers (such as Servientrega, Inter Rapidísimo, or Envía), pack the clothes in a sealed plastic bag inside the box to protect them from humidity during the journey. The golden rule is clear: never send the package or hand over the garments until the payment is effectively reflected in your bank account. Do not rely solely on screenshots of transfers; if you want to make everything clearer, check this guide on proof of delivery and dispute prevention.

Frequently asked questions

❓ Where can I sell used children's clothing in Colombia without paying a commission?

On Colombia Move, you can sell children's clothing for free and without commissions. Unlike GoTrendier, which according to their cost list consulted on July 9, 2026, charges 9.99% + $3,999 COP (plus VAT) per sale, on Colombia Move the deal is direct.

❓ How are children's clothing sizes determined in Colombia?

Baby sizes are classified by months and older children's sizes use numbers. According to size guides from Baby Fresh and Falabella consulted on July 9, 2026, Size 4 is equivalent to about 104 cm and Size 6 to 116 cm.

❓ What is better: selling by individual items or in lots?

For basic items like bodysuits, t-shirts, and everyday pants, it is much more efficient to sell them in lots (bundles) of the same size. More expensive items, such as winter jackets, party dresses, or branded coats, sell better individually.

❓ How should I set the price for used children's clothing?

In 2026, a prudent starting point is between 30% and 50% of the original retail value. Adjust based on brand, condition, season, and whether you are selling in bundles; avoid promising exact profits because every buyer compares differently.

❓ Which children's clothing brands are in highest demand in the secondhand market?

Brands known for durability tend to move better, but there is no guarantee of a quick sale. Baby Fresh, Offcorss, EPK, Carter's, Zara Kids, and H&M usually build trust if you show the label, actual size, and fabric condition.

❓ How do I sell safely and avoid disputes when delivering used clothing?

In 2026, for local deliveries, agree to meet in a busy public place. If you are shipping nationally, use recognized courier companies in Colombia and never send the package before verifying that the payment is reflected in your account.
