I was going to suggest the same things, Laura!
I think it's often all down to accessories. Just by wearing those dresses (which are lovely on you, btw) with boots instead of a more classic heel already ups the hip ante, I think. I even think the way you're wearing them in the photo, belted at the waist, is making them look more modern than they would if they were worn as-is.
So, moving forward from that, how about a very cool, unexpected bag? Something oversized, or bright perhaps? What do you have in the way of funky jewelry? Oh, and legwear- sometimes I'll wear an otherwise boring dress with coloured/patterned hose and it usually livens it up somewhat. Basically, I think the trick is not to wear too many "classic" items together at one time. It's the mix of styles that makes it modern.
I'd also like to see Angie take on the classic wrap dress! I don't have a DVF, but her classic black collarless style (I think it's called the "Julien") has been on my wish list for years. One day!
