Discussion with friends. Very heated disagreement. Unreasonable wearing knickers . Reasonable not wearing knickers

You need to say which is unreasonable. Knickers or no knickers. I say definitely knickers or you have to change your PJs constantly

I think it probably depends when you tend to wash and the type of nightwear you prefer? I’m firmly in the ‘no knickers’ camp but I shower in the evening and wear loose pyjamas bottoms so I only change my pyjamas every 3 nights 🤷🏼‍♀️

Ihatemondays1962 · 22/11/2025 20:53

No knickers but I do change pj's every couple of days.

Myoldbear · 22/11/2025 20:53

Knickers!

Happyher · 22/11/2025 20:54

This is why I don’t wear pyjamas. Unhygienic with none if you wear them more than once. Itchy and hot if you wear them with knickers

sploshsplash · 22/11/2025 20:54

it all depends on the day 🤷‍♀️

AMBOG · 22/11/2025 20:56

You will be shocked to know my very dirty friends don’t wear knickers and only change their pyjamas once a week!!!

I find the “airing out” point odd. You’re still wearing pyjamas, and you’re under a duvet, how much airflow is there??

CrowsInMyGarden · 22/11/2025 20:56

I don't know if we are talking about lounging around in the evening - in which case it would be knickers and pjs, or actually sleeping in bed - in which case neither, just a T shirt

pinkstripeycat · 22/11/2025 20:56

Wearing knickers with PJs would make me sweat. Also they’d go in to my creases so definitely no. My PJs are very loose and go nowhere near my crotch so usually wear them twice.

TheBlackSheepbaaaa · 22/11/2025 20:57

Shower in the evening and then it's knickers and pyjamas for me. I change my pyjamas every 2 days.
Although, I tend not to wear the pyjama bottoms in bed because they annoy me, have recently started wearing leggings in bed instead, they're so comfortable! Still have my knickers on underneath though.

ShodAndShadySenators · 22/11/2025 20:59

I wear my pyjamas two nights; first night knickers underneath, second night none but they're straight into the washing basket. If I got sweaty on the first night, which might happen in summer, I don't go a second night.

My nethers aren't arsed about getting an airing, there's been no complaints.

IvedoneitagainhaventI · 22/11/2025 21:02

It was only when I was in my 30s and in hospital did I find out some women actually wore knickers under their nighties.
And then only since I started reading MN threads a couple of years ago I found some women wear knickers under their pyjamas !
Goodness knows what the next revelation will be.

One of the joys of getting ready for bed is getting all the restrictive underwear off! I slept nude for many years, graduated to pyjamas, but now prefer a nightie. No knickers.

People have some very strange discussions with their friends

If you think this is a strange discussion you would be horrified if you heard some of the things my close friends and I discuss!

Jollyjoy · 22/11/2025 21:04

This is one of those MN regular threads but always fascinates me! I was brought up no knickers, and if I ever have to wear knickers like on period sometimes (if v heavy, usually I just use Mooncup so still no knickers) it feels hot and restrictive. Having air and space down there feels better. Change jammies every second night. Shower most days. My vagina is not a disgusting smelly place as some people seem to think vaginas are!!

CarlaLemarchant · 22/11/2025 21:05

Knickers but I tend not to wear pj bottoms in bed as my legs get too hot.

ExhaustedPigeon37 · 22/11/2025 21:06

Never wear knickers (unless on my period and still then find it uncomfortable then!) with my PJs or in bed to be honest! We are both (DH & I) are naked sleepers!

Londonrach1 · 22/11/2025 21:07

Why wouldn't you put pants on under your pj's. Do people go naked in their pj's. Yuk. Do they not wear pants in their day clothes too .. strange. Made up mn thing surely. Everyone wears pants

dementedpixie · 22/11/2025 21:07

No pyjamas or pants for sleeping. I put pjs on in the morning with no pants

Idontknowhatnametochoose · 22/11/2025 21:08

Knickers because I often get hot in bed and take my pj bottoms off. I dont want to be starkers as that feels unhygienic.

pumpkinscake · 22/11/2025 21:08

What do you vote if you don't wear either knickers or pajamas?

Itiswhysofew · 22/11/2025 21:08

No knickers and change pyjamas everyday. DM never allowed us to wear knickers to bed.

JLou08 · 22/11/2025 21:09

No knickers!
I was advised by the midwife that it can contribute to thrush.

Brightbluesomething · 22/11/2025 21:09

I don’t think I own any knickers I could wear under pjs. I used to have great big maternity granny knickers after giving birth but now I only have thongs and a couple of pair of ‘suck me in knickers’ for particular outfits. I do change pjs every couple of nights though.

My mam always told me to air it at night and not to wear anything too tight as you’d overheat and get thrush. Same with socks, none at night to help regulate your temperature. Although I do have some big fluffy ones for the depths of winter.
No idea if there’s any scientific basis but I tell my DD to do the same.

Knickers but no pyjamas!

Neither for me. Hate sleeping in any kind of clothes

Pollqueen · 22/11/2025 21:09

Doggielovecharlotte · 22/11/2025 20:44

My mum always taught me to “give it some air” so no knickers for me!

This. Air your bits at night
