What does your style say about you? Not - how do others perceive you on the basis of your appearance - that's a loaded and potentially damaging question. Rather, when you're choosing a new wardrobe addition, is your choice based solely on function, comfort, availability - or something else?
There are many reasons behind my apparel choices, but here's one I rarely share: I personally choose clothes that are elegant to the point of intimidation. As a student (with a relatively typical jeans-band tshirt-cardigan wardrobe to match), I grew tired of the easy familiarity with which unsolicited men approached me, and the daily barrage of harassment. I felt too approachable in 'ordinary' clothing, and resolved to wear garments that conveyed a sense of remote intelligence. With vague ideas of 80s power dressing (but a dislike of the fashions), I turned to mid-century skirted suits.
And it worked. Catcalls and other inappropriate behaviours are rarely targeted at me anymore, and consequently I feel much safer. Rather unexpectedly, I'm often deferentially addressed as 'ma'am', doors are opened and train seats vacated. There is of course, an important discussion to be had (and societal changes to be made) on the prejudices behind the how and the why, but I'll leave that to the social commentators.
Sometimes I fear it has worked too well. Once at a coffee and catch up with a female friend, two of her male acquaintances dropped by. Both shook my hand, and one proceeded to sit and join in our conversation. The other remained standing and turned around to face the wall. A 32 year old man with a high-flying career literally could not look me in the face. He later informed my friend that he was very intimidated by me and could he buy me dinner? Oh dear.
