When I transitioned the first time, I lived and worked as a woman for a little over 2 years and part of that was for a UK Bank. At that time they had a dress code for women which was only a skirt or dress, with pants disapproved of, and the skirt or dress was expected to be no more than 2" above the knee or below it and wearing stockings or tights was mandatory, nude, tan or black was acceptable. We were also expected to wear low heels, with a maximum of 2.5". Flats were also disapproved of. I am sure looking back it was to ensure the women conformed to what the men in the Head Office expected. Soft colour blouses were encouraged and we were expected to wear a jacket unless in summer if wearing a skirt and blouse. With dresses, bare shoulders was frowned upon , but sleeveless was acceptable, but woe betide any women that hadn't shaved or had her armpits waxed. I loved it as I was able to express my femineity, but a few of the women I worked with used to complain it was all for the men in the office benefits!
