Rules are made to be broken. Especially rules about fashion. Historically, anything goes when it comes to style—from women’s trousers to men’s skirts and everything in between. Alexander McQueen famously claimed that there are no rules when it comes to fashion today so why not shake things up in the name of style? Here, we give you five former fashion no-nos that bold designers and brave celebrities have disregarded and teach you how to be a rule breaker yourself, provided by Bank Fashion.

No White After Labor Day

I can hear my mom saying it now: “No, you cannot buy those white Mary Janes for the first day of school because you cannot wear white after Labor Day.” It annoyed me then and it annoys me now. Who’s to say that we shouldn’t wear white after the first Monday in September? Although the origins of the rule are rather mysterious, celebrities and fashionistas like Kim Kardashian seem to pay no attention to it. Now winter whites are not only accepted, they’re embraced. And what would look chicer in the snow than a white pea coat or more glamorous at a party than a white evening dress?

Don’t wear navy blue and black

Navy blue and black are two colors that when imagined together conjure up images of huge bruises, which is exactly what a friend of mine said wearing navy and black together made her feel like. But this rule has recently become outdated and dumb. Navy blue and black, two neutral, dark colors, can look extremely chic when combined together in the right way. Victoria Beckham pairs them all the time and you can, too. If you’re afraid to go all out, try wearing a pair of black tights with a navy skirt or dress, or accessorize a navy ensemble with black accessories, such as black leather flats and a black tote.

You must match your leathers

Who has time to make sure that the color of their leather belt matches that of their shoes and that of their handbag as well? This rule is so boring. Mix it up! Hayden Pannetiere did it well by pairing brown leather riding boots with a black leather jacket. You can now wear a black leather handbag with brown leather flats a red leather jacket and not have to worry about whether or not you look good—because you do.

Don’t mix clashing prints and patterns

If you pay attention to the fashion world at all (which we know you do), you’ve probably noticed that when it comes to prints, more is, well, more. And that’s a good thing. Fashion show fixtures like Leandra Medine have mastered the art of pairing together clashing patterns, prints, textures, and colors in a way that’s fresh and chic. If you’re worried about looking like a clown, take it slow. Mix a camouflage blouse with a non-neutral bottom, such as purple trousers or a red skirt. Horizontal stripes paired with florals is always a safe bet when it comes to mixing prints.

Dresses and trousers should not be worn together

Thoughts of skirts or dresses over trousers bring to mind images of grungy, 90s rockers with long dirty hair and band t-shirts. That is, until Emma Watson wore a black strapless dress over black trousers at the premier of The Perks of Being a Wallflower. The result? Über-chicness. This is a very edgy look, so if you’re going to try it definitely stick to one color—and make sure it’s a neutral one. Black or white is a safe bet. Make sure the pants aren’t too baggy and the dress isn’t too tight, and pair it with some heels. Voila, you’re a trendsetter.
