UNIQLO Uniqlo Ultra Stretch Set Size M Gray Long sleeve, long pants Loungewear or pajamas Purchased new from the Uniqlo official website. I followed Uniqlo's recommended size, but the sleeves were too short, so I'm selling them. Both top and bottom have been tried on once. Thank you for looking. Please consider that this item has been in someone's possession once, and that it has been stored at home by a private individual. Thank you for your understanding.
