I wear polos, jeans and sometimes even t shirts to my work and I haven't had a haircut in years. I shave about once every week or two. I don't miss suits and definitely don't miss the corporate choke chain that is the neck tie......but from my experience, workplaces which have asked me to suit up in the past have also requested a professional standard of dress from women.
If OP wanted to dress like the women in his workplace he probably could....especially if he's armed up with a good discrimination lawyer
Interesting note: When women do wear suits of any kind, many people complain corporate roles are stripping women of their femininity. Some will always find a complaint when it comes to sharing the workplace with women.
It's the 21st century. Women work. Let's accept it. I personally don't give a crap what anyone wears to work. If I made the rules we'd all be allowed to work in our undies if we so desired .....or more modest people could wear hessian sacks. I really couldn't give a fuq.
