YANBU. Some people (especially a generation or two older,) seem to NEED to tell us their opinions and views, whether we ask for them or not.
I used to get comments on what I eat, (from relatives,) but what pisses me off to fuckery is well meaning women (always women!) over 60, telling me I MUST be cold and I NEED to wrap up better.
One woman (the mother of a woman I know,) barked at me in Tesco the other week 'OOOOH, for goodness sake, cover your chest! You will catch your death of cold!' (I had a V neck top on, and a thick cardigan, and a coat with a hood on it. So I was wrapped perfectly well. And it was about 9 degrees C.)
The woman I know looked embarrassed and mouthed 'sorry!' ... to me. I did just laugh it off, but I have lost count of the amount of women who have said 'OH MY GOD, you must be FREEEEEZING!
You need to wrap up more.'
FFS, I am nearly 50, and I don't need to be told that I not dressed correctly. 
I used to get it from my mother - comments about me needing to put more clothes on, and she always came out with the passive aggressive comments aimed at my kids too..
'Awwww poor little girl, hasn't your mommy put a coat on you? You look sooooo cold, you must be freezing with only a t-shirt, cardy, and leggings on!'
(I was only taking them from the car to the front door; about 20 feet!) SO ANNOYING!
Just ignore them OP. What you do and don't do, is none of their business!
