Some people are batshit, and also very nosey and intrusive and think everyone they meet needs their opinions and views.
I have had about half a dozen women approach me in the last few years (I am in my early to mid 50s,) and TELL me I need to wrap up, asking where is my coat? TELLING me I should not be wearing open toed sandals in 'this weather,' (a bit wet and 10 degrees C), and shaking their head and saying 'dear me,' and pointing at my cleavage. Obviously annoyed at me showing a tiny part of my breasts. Probably the same women who attack mothers who are breastfeeding. I think they're afraid their husband will look.
Some are about 10-15 years older than me, so they think they have the right to talk down to me/talk AT me because I am younger. And some are 10-15 years younger, and they probably think I am some daft fruitbat who can't dress herself properly because I have a short sleeved t-shirt on with my jeans, and open toed sandals - and it's only 10-12 degrees C. I'm not going out like this in minus 7 temps, I am not cold. I don't get cold easily, but I do get HOT. Also, I will dress how the fuck I want. I don't need anyone's fucking approval.
One woman (when me and DH were on a day trip last September, and it was 14 degrees C, and a tiny bit breezy,) stepped in front of me as me and DH were walking, and STOOD in my pathway, and said 'why on EARTH are you not wrapped up better, Where is your coat?!' with this look >>> 
I had a short sleeved shirt on and jeans and trainers. She was about 5-10 years older than me, and was demanding to know why I had bare arms.
I just shook my head and sort of snorted, and half laughed, and walked off. She was not worth my time. Like, who the fuck did she think she was? My DH stood next to her said 'oh she doesn't feel the cold really, in fact she's always hot, and it's not that bad today.' 
I called over to him and said 'why are you talking to this person and WHY are you explaining anything to her? What I wear has got fuck-all to do with her!' And I walked off ... I was fuming with DH for 'explaining' to her. I said 'next time you walk off with me. and IGNORE them.' And there will be a next time because this has happened at least half a dozen times in the past 4-5 years. It's always a woman too. Telling me how I should be dressed.
I don't know who the fuck these women think they're talking to. But I won't be told what to do/how to dress, and I won't be talked at. I ignore them, or give them a short shrift. They are as bad as the 'smile it might never happen' men and the 'random men' who try and talk to you by saying banal stuff, and throwing in unwanted opinions.
They are not in ANY WAY 'trying to be nice.'
