is this sexist to be commented on every morning

[moomoome]

every morning i go into work the man i sit next too needs to comment on what im wearing. i work in a professional job and always wear professional dress. many of my colleges wear t-shirt and jeans etc. im aware that my background (Hertfordshire girl, mostly dresses) makes me a bit different from my rural Australian female colleges (pants and shirt). but is this not a bit sexist to greet me with comments about my dress? his comments im sure are kindly met but he and the boss see no issue in this. i find it extremely sexist as my ability to do my job is not based on what i wear.

I think he's unreasonable to comment all the time. I think I'd respond in kind so he gets how weird it is, example:
Ah moomoome I see you're wearing the dress and tights today.
Er, yes Dave and you're in jeans and t-shirt?!

BuffytheReasonableFeminist yup, shit isn't it? It is slowly getting better I think, but there are still a lot of racist, sexist idiots in country Oz.

I'm not sure the fact that he doesn't say similar comments to other women is an indication of him not being sexist. The fact is he is singling out a woman to make comments on about her appearance everyday. He wouldn't single out a man for the same treatment. I would imagine that would be considered very weird generally and probably wouldn't even cross his mind no matter how the man was dressed.

the kindest interpretation is option B

We don't have to be kind.

(slightly off topic, but it's no less true)

No, we don't have to be kind. I try to be, though, as a general rule (and not just to men re: compliments)!

One can have boundaries (i.e. pushing back when comments make you uncomfortable, however well-intentioned) and still be nice to others.
