Undergarment exchange policies can vary from store to store, but generally, they are more restrictive than exchange policies for other types of clothing. Due to hygiene concerns, many retailers do not accept returns or exchanges of undergarments that have been worn or washed. Some stores may only accept exchanges for unopened packages, while others may allow returns or exchanges only for undergarments that have manufacturing defects. It is important to check the store’s exchange policy before making a purchase to avoid any issues with returning or exchanging the item later. Additionally, it is always recommended to try on undergarments before purchasing them to ensure a proper fit and minimize the need for returns or exchanges.
