How to Ship Clothes You Sold Online

Packaging: poly mailers vs boxes

The right packaging depends on the item. Most clothing ships best in poly mailers — they're light, waterproof, and cheap. Save boxes for structured or fragile items.

Buy poly mailers in bulk (100-pack) from Amazon or eBay for the best per-unit price. Always place the garment in a clear poly bag inside the mailer for moisture protection.

Folding techniques that reduce damage and shipping costs

Proper folding keeps items compact (lower shipping cost) and presentable when opened. A buyer's unboxing experience affects their review and whether they become a repeat customer.

1. T-shirts and tops — Fold in thirds lengthwise, then fold in half. This fits a 10x13 poly mailer perfectly.
2. Jeans and pants — Fold in half at the waist, then fold legs up. Roll for extra compactness if shipping weight is a concern.
3. Dresses — Fold lengthwise, then fold in thirds from the bottom up. Place tissue paper between folds to prevent creasing on delicate fabrics.
4. Blazers and coats — Turn inside out, fold one shoulder into the other, then fold in half. Ship in a box if possible to maintain the shoulder structure.

Shipping carrier comparison: USPS vs UPS vs FedEx

For most clothing shipments within the U.S., USPS offers the best rates. UPS and FedEx become competitive for heavier packages over 5 lbs.

Use Pirate Ship (free to sign up) to access discounted commercial USPS and UPS rates — typically 20-40% cheaper than retail counter prices. Weigh your packaged item with a kitchen or postal scale before listing so you can set accurate shipping costs.

Platform-specific shipping: how each platform handles it

Each resale platform handles shipping differently. Some provide prepaid labels, others let you choose your own carrier. Knowing the details helps you price accurately.

International shipping: is it worth it?

International shipping opens your inventory to a global buyer pool, which is especially valuable for rare vintage and designer items. However, it adds complexity and cost.

1. USPS First Class International — Cheapest option for items under 4 lbs. $15-25 to most countries. Tracking is limited and delivery takes 2-4 weeks.
2. USPS Priority Mail International — $30-60 for most clothing items. Full tracking and delivery in 6-10 business days.
3. Customs forms — Required for all international shipments. Accurately declare the item type and value. Under-declaring value is illegal and voids insurance.
4. eBay Global Shipping Program — The easiest option. Ship to eBay's domestic hub, and they handle international forwarding, customs, and returns. The buyer pays all international fees.

For most sellers, start with domestic-only and add international shipping once you have your process dialed in. The exception: if you sell rare vintage or luxury items, international buyers may be your primary market.

Insurance and tracking for high-value items

Always insure items worth $100 or more. The cost is minimal compared to the risk.

USPS Priority Mail includes $100 of free insurance. For higher values, add coverage through the carrier or Shipsurance. For luxury items like Hermes bags, Chanel bags, or Louis Vuitton bags, the insurance cost is always justified.

Shipping tips that reduce problems

1. Weigh before listing — Use a kitchen scale or postal scale. Price your shipping based on the actual packed weight, not a guess. Underestimating by even half a pound can cost you $3-5.
2. Ship within 1-2 business days — Fast shipping earns better reviews and boosts your seller ranking on most platforms. Poshmark penalizes sellers who consistently ship late.
3. Include a thank-you note — A handwritten note costs nothing and increases the chance of a 5-star review. Top sellers report 15-20% more repeat buyers when including a personal touch.
4. Track everything — Always use a service with tracking. Share the tracking number with the buyer immediately. This protects you from "item not received" claims.
5. Save your receipts — Keep shipping receipts (digital or physical) for at least 60 days. You'll need them to file insurance claims or dispute chargebacks.
