When shopping on AliExpress, a global e-commerce platform, U.S. consumers often encounter challenges related to product sizing, particularly for apparel and footwear. The platform itself does not offer a direct size-change feature after an order is placed. According to the provided source material, if a consumer realizes they have selected the wrong size, the recommended course of action is to contact the seller directly. This approach is more likely to be successful if the seller's store is geographically closer to the buyer's country, though this is not a guarantee. The source emphasizes the importance of checking the seller's reputation and positive ratings before purchasing, as size charts provided in product descriptions may not always reflect the true measurements of the item.
If a significant discrepancy is discovered after receiving the product—where the actual measurements differ visibly from those listed in the description—the platform's dispute resolution process is the next step. The source indicates that opening a dispute allows AliExpress's support service to mediate. The process may take several days, but filing a complaint can lead to assistance from the application's support team.
Regarding the exchange of a product for a different item, the source states that AliExpress does not provide an automatic exchange option. The most straightforward method to obtain a different product is to cancel the original order and then place a new order for the desired item. To cancel an order, a consumer can use the 'Request cancellation of the order' option, which is available in both the web version and the mobile application. Once requested, the seller typically has a 72-hour period to confirm the cancellation. If an agreement is reached with the seller through direct communication, it is possible they may send a shipment with the changed product, but the fastest method remains canceling and reordering.
The source material also provides extensive size conversion charts for various categories of apparel and footwear, which can be used as a reference when placing orders. These charts cover women's clothing, men's clothing, lingerie, underwear, and shoes, with conversions between Chinese (cm), American, British, European, French, Italian, and Japanese measurements. For example, women's clothing sizes are listed with Chinese height and bust measurements corresponding to international, American, and European sizes. Men's suit pants are detailed with waist and length measurements in centimeters for specific size numbers. Footwear conversions include Chinese, American, and Japanese (cm) sizes for both women's and men's shoes.
