I didn't respond to this thread yesterday because I really had to think about the question. I'd say my "signature" look, if you can call it that, is:

*wardrobe consists of subdued, elegant colors
*wardrobe consists of some trendy items mixed with classic styles
*easy hairstyle above shoulder length
*always wear jewelry and a wristwatch
*almost always wear makeup

i don't know if this is specific enough but I *need* contrasts like mixing classic pieces with vintage and/or some rough elements. i'm also thinking contrasts structure wise, like combining tailored with a softer element. too polished and ladylike feels very unfamiliar to me

ETA: maybe dark hair is more of a signature feature? sometimes I've had highlights or coloured stripes, but the main feature still remain as dark

Short hair. (Why did I every grow it out??) But the particular cut will change over time.

Jackets. (Why did I stop wearing them for so many years?)

And Una, that hairstyle of yours is definitely iconic!

bright colours, blunt bangs, oversized glasses, big bags (clutches + totes), hats or hair jewellery (sparkly + subdued), cardigans, flats.

I thought about this quite a lot and found that I had a hard time. I don't think I've been actively working at being stylish long enough to say, and I enjoy incorporating new trends each season. But reflecting on my style preferences from when I was younger through today there are a couple things that have remained consistent:

- color (I've always loved wearing color, and wearing interesting combinations especially)
- the idea of experimentation (I have always liked experimenting with my outfits)
- styling my skin/face/hair in a natural and organic way (minimal makeup, light hair styling relying mostly on cut)
- the influence of 70s fashion (my other influential decades, 40s/60s/80s, have varied over time in how much or how little they're represented, but the 70s have always been present)

That's about it. Ask me again in 10 years
