If the clothes you buy are under warranty, don't deal with them yourself first. Take the receipt to the store you bought at that time and let the clerk see why. If it is a quality problem, it can be replaced.

? If the warranty period has passed, it is recommended to use epoxy soft glue to stick it by itself. This is a liquid, two-component, soft, self-drying soft adhesive, colorless, transparent and elastic, which will automatically recover after the surface is slightly scratched. Suitable for sticking decorative signs such as polyester.
