Is it normal to not wear underwear under pajamas?
Yep.Totally normal
Yes, it’s totally normal to sleep in pajamas without underwear. It mostly comes down to comfort and personal preference.
Lots of people skip underwear under pajamas, while others prefer the extra layer. Neither choice is unusual—wear whatever feels comfortable to you.
Just change and wash your pajamas regularly, especially if you sweat at night. Breathable fabrics can help keep things comfortable, too.
