Oh yes!
I used to be in one of those 'liberal' workplaces, but it tied me down or cut me up stylistically to the point where I'm very leery of working for such an organization ever again. It was a publishing group that brings out lifestyle magazines, including a couple of international fashion magazines for women. I was *told*, on the one hand, that I needed to be dressed on-trend; on the other, as one of the youngest and definitely the shortest 'seniors' on the editorial team, I had to dress for authority and extra maturity, a la Gaylene.
Most days, I actually dressed in a way that had me feeling either out of sorts or dull enough to disappear. Just NOT my speed, with too much denial of what IS! (Dressing 'Indian' was out, I was told in no uncertain terms. And I'm not comfortable with trendy, though sometimes I can be weirdly fashion-forward to the point that the average 'trendy' person finds me inexplicable and unspeakable.) ::shudder::
Nowadays, I have a whole lot more freedom, but like Suz, working from home means I actually miss dressing up a little more! I'm not a 'dressy' person usually, but anything too delicate or pale or tailored --- all of which I sometimes crave --- can be problematic for my daily life because I'm (a) clumsy in the cooking and cleaning and gardening which are interleaved into my working day, (b) fighting with high heat and humidity, sans central air-conditioning, most months of the year, and (c) barefoot and cross-legged half the day but walking through decidedly mucky, messy country roads the other. :-/
I'm... still adjusting my style to suit!
Btw, note that UWP Rae, one of the first of that tribe, used to work in a bank...! She's been GREAT at the balancing act, truly inspirational. You might like to explore some of her older threads, especially one where she looks back at dressing UWP with a dress code.
