In keeping with my Gentlewoman style moniker (aka Grown Up Tomboy), the only times I have consciously copied a style element from a real-life source, it's been from a man.
The first time... Back in the Dress-for-success 80s, trying to find my sartorial niche, I was captivated by the cardigans worn by a private-school-teacher friend. Now they're called grandpa or boyfriend cardigans, but back then they had no name and were like hen's teeth to find in women's clothing. But I eventually succeeded, and have had a couple in my wardrobe ever since.
Fast forward a few decades... Still trying to figure out how to add a third piece comfortably while wearing a white coat over top: I noticed one of my male colleagues had perfected the shirt-and-sweater-vest uniform, and I followed suit. Great solution to the gaping shirt at the bustline problem. Over time it evolved into the shorter vest over untucked shirt proportion (as younger guys joined our group and showed how).
Then, about 5 years ago, I was at a day-long meeting to discuss government policy (at which nothing I said could make a difference). My wandering eyes checked out how the other women were dressed. Then I noticed one man wearing classic loafers without socks, and when I got home I dug out my black patent loafers and started wearing them sockless with everything, followed by several new pairs, and then they started trending.
Forward to my latest inspiration, this time at a concert of Renaissance music. The musicians were in all black of course, and soft-soled black leather shoes, because of all the foot-tapping. Except for the leader and setar player, who wore dreadlocks and a full beard, and a colorful shirt that was both boho and subdued. And HIS shoes had red laces that made me smile. Now all I need is the right width of red ribbon, and my 2 year old black patent oxfords will go from boring to just the kick my fall and winter wardrobe needs. (Without my spring/summer blues and navies, my closet is over 90% black, grey, and red.)
Anybody else find their inspiration in weird places?
