You want like a list?!
Not so much "unladylike" as "age inappropriate" according to my mum - having my hair long now I'm past the age of 40! I'm 50 next year and I'm not cutting it!
She doesn't like that I'm happily single
Wearing trainers
Not shaving my legs (or anywhere else)
Not ironing (I don't even own an iron since dd left school, mum thinks this makes me a complete slattern)
She couldn't understand my breastfeeding past 6 weeks, apparently that's plenty
Swearing isn't an issue, she's Glaswegian she can turn the air blue faster than a sailor!
made for some...interesting incidents when the grandkids were learning to talk 
Tattoos and piercings aren't an issue either as she has a few herself.
My mum doesn't know about any of the fwb or Ons or flings I've had since splitting from ex, she thinks I've been celibate for 19 years!! 
ooh if she only knew! She'd be horrified!
Going to nightclubs - 'you'll never meet a decent husband there - why don't you join the Young Conservatives?' !!!!!!!!
She may have a bit of a point, met my ex at a club. Met my previous ex via an activist group aka protestors event! Fuck knows what your mum would make of that, I know mine wasn't impressed! With either scenario!
But she hates me being single even more, her suggestions for "nice" places to meet men have included:
Doing am dram
Getting a nice little part time retail job (I had a full time well paid admin role related to my degree at the time)
Join a rambling group (I have no interest in rambling)
Ballroom dancing!
Regarding my leaving ex for infidelity (didn't tell her straight away for obvious reasons I think)
"But are you sure he cheated? He might only have been...tempted?"
"Yes I'm sure the baby that's due in a few months is final proof"
"But it might not be his" 🙄
Gimme strength!
