I think it's a personality thing. My hair tends towards frizzy, too, and I til ghds were invented I looked terrible. But as I got older, I started to embrace my messy, wavy hair, and my general intolerance of high maintenance looks.
A carefully-pressed white shirt and straightened hair will stay looking good on me for half and hour or so until I move too much, or go outside and encounter weather.
Wavy hair, natural, slightly dewy make- up, a fabulous hat, a nice textured cardigan, or leather or velvet jacket, a silk shirt or comfy jersey top, wide legged tweed trousers, comfy shoes and lots of pearls works far better on me, and are mostly vintage.
I'm not waifish enough to carry off the boots and floaty dresses of my teens, but I wear a slightly more structured version of the same basic style. Basically, I can't get away with polyester as much as used to.
