When we think of classic style icons, they tend to remain exactly that - as icons, rather than people whose style we can borrow for our own outfits. Perhaps because they're so revered, the looks they made famous don't seem achievable - but I don't think that's always true. There are some - Madonna's conical bra, Daphne Guiness' extravagant couture ensembles - that won't translate so well to the day-to-day, but there are others that certainly do.
1. Audrey Hepburn
There's a reason Audrey Hepburn is always featured on any style icon list, and that's because she managed to nail a personal style that transcends time and money. You don't need a huge budget and you don't to be into a vintage look to work it into your wardrobe. Think classics; the LBD, full skirts, espadrilles, black cigarette pants and Breton tops.
