I've been trying to figure out how to put together more sophisticated outfits and/or buy more sophisticated items, but I'm having real trouble defining exactly what "sophisticated" means. It's one of those "know it when you see it" things but I really want to nail it down a bit better. I realize it may mean slightly different things to different people.

My "benchmark" of sophistication is a photo I remember seeing of Jackie O. She was pushing one of Caroline's kids in a stroller down 5th avenue (NYC) and was wearing a slim black coat, black slacks, black tie shoes, her signature large sunglasses, and "done" hair. That woman was sophisticated in her sleep, I'm sure

I found this definition in merriam-webster online, but it's one of those "self defining" definitions that is not helpful...-

- having or showing a lot of experience and knowledge about the world and about culture, art, literature, etc, attractive to fashionable or sophisticated people, highly developed and complex

How do you define sophisticated in terms of fashion and style? What are the characteristics of sophisticated wardrobe items and outfits?

would love to hear your thoughts.
