Yup - I completely agree with the observation of historical influences in fashion. I think I blogged about it - I'll post some of my observations here anyway.
Historical influences - not just ancient, medieval, or Renaissance influences but the 60s and 70s as well.
Take Versace, for example:
(from style.com) 60's retro sort of look.
Or how about Alexander McQueen?
(Style.com) 18th century? Modification of classic British styles?
And even Dolce&Gabbana:
(Style.Com) Military style, Napoleonic times - it was mentioned in the Style.Com video, but I think it's quite clear from the picture as well.
But it's not just historical influences, I think. I believe the rocker-chick look is coming back into chic -
Dior, of course.
(Style.Com) The 70s thing is also applicable - it's a historical influence, after all, but it's also a rock thing.
And Gucci as well.
(Style.Com) Don't you find it quite rock-and-roll?
Anna Sui, perhaps?
(Style.Com) I don't think it's explicitly mentioned anywhere, but I think the rock theme's quite heavy at Anna Sui too.
And based on most of the photos above, I think wide belts or very flashy ones are in again.
