"Jammieses" is colloquial for "pajamas," but there are plenty of other synonyms to describe this cozy sleepwear. Some alternatives include "sleepwear," "nightclothes," "nightwear," or "bedtime attire." "Lounge wear" or "comfy clothes" can also be used to describe clothing suitable for lounging around the house. For those who prefer a more vintage or classic feel, "nightgown" or "nightdress" might be more appropriate. Some people may even simply refer to their pajamas as their "jammies" or "PJs." No matter what term you use, comfortable sleepwear is essential for a good night's sleep.
