Everyone has heard at least one old fashion rule. Have you ever been told not to wear white after labor day, or that your jewelry metals must match?

If you're like me, you grew up hearing these from your mom or grandma whenever you wore something they didn't like. You thought your outfit was fine, but one of the rules probably made you rethink it. Many of you may still believe one or two of them, because you've heard them so many times.

Believe it or not, most of those fashion rules are completely outdated and false!

As someone who loves fashion but doesn't believe in old-fashioned rules, I say it's time to put some of these style myths to rest once and for all. It's the 21st century, and grandma's fashion rules just don't apply anymore.

Here's the CF list of fashion rules you're allowed (and encouraged) to break:

1. Never wear white after labor day.

This fashion rule is probably the most pervasive of them all. Everyone's heard it, and surprisingly, lots of people still believe it's true.

Newsflash: you can absolutely wear white after labor day! White clothing, coats, bags, and even shoes are 100% allowed during the winter months, and don't let anyone tell you differently. Unless you have an extremely conservative workplace, you should embrace the idea of wearing a "winter white." It's a fresh, fun break from the dark shades we usually wear in winter.

InStyle magazine did a great feature on fashion rules the stars love to break. In it, Rachel Bilson sounded off on the white after labor day rule, saying "Forget the old rules. I love white all year round. It's cooler to wear it when you aren't supposed to."

For another star example, check out the picture of Victoria Beckham above. She's a world-renowned fashionista who's known for her impeccable style! She doesn't follow the white after labor day rule and neither should you.

2. Shoes and bags must always match.

Ugh, this rule is sooo 1950s. I'm honestly wondering if anyone out there still believes this one.

In case you did think this myth was true, let me reassure you.. it's not! You don't have to match your shoes to your bag - that's so boring. You shoes and bag need to go with your outfit, but there's no reason they need to match each other. So long as they work with your outfit, they can be any colors you want.

Let's be realistic - can you imagine what a pain it would be to match all of your bags to all of your shoes? You'd probably have only one or two combos you could make, and even then, it probably wouldn't all match perfectly. There are so many shades of each color!

Really, it's all way too much of a hassle. Forget about matching and start thinking about what goes together and what goes with your outfit.

3. Never wear black with brown or navy.

This rule is one of the most pervasive old fashion rules out there, and it's just not true at all!

Here's the deal: black, brown, and navy are all neutrals. This means that you can wear them with pretty much anything, including each other!

I love the look of a navy blue dress with black shoes, or a black dress with light brown or nude shoes. Anything goes with these colors, and you should feel free to mix 'em however you want.

Recently, Rihanna made a public statement about this rule:

"The idea of not wearing brown and black together seems so dated. The other day I wore a black T-shirt, black Nobody jeans, a brown leopard-print belt by Dolce & Gabbana, and brown Giuseppe Zanotti shoes, and it looked awesome. And I also love to mix prints."

For another example of a celebrity breaking this rule, see the photo of Rachel Bilson above, mixing navy, black, AND brown. Her outfit looks adorable and fashion-forward, proving that this rule is really just a dumb myth.

4. Never wear red if you're a redhead.

This one might have some basis in reality, but it only applies to a few people in certain situations.

It's true that some redheads don't look their best in some shades of red, but it's completely false that they can't wear red at all. If you have red hair, you need to be extra careful to choose reds that work with your natural coloring. The wrong shade can look too intense, and can clash with your skin. It's as simple as that. (By the way, this same thing could be said for EVERY hair color!)

At the end of the day, if you know the best colors for you, you can avoid shades of red that don't work, and wear the ones that do. The idea that you can't wear red at all is completely FALSE!

5. You can't wear suede or leather in summer.

Another false one. Really, who comes up with this stuff?

I don't know about you, but I would be LOST without my leather bag in the summer. Most of the world's best shoes and purses are made out of leather, so it really makes no sense that we wouldn't be able to wear them year round. Also, leather jackets are such a hot trend. It would be a shame to have to put them in the closet for 3 months!

If you're really worried about this one, just pick lighter weight fabrics and go with lighter colors of suede & leather for the summer months. Then switch back to your regular stuff for winter.

But really... the next time someone tries to convince you this rule is true, just laugh and ask if you can borrow their most expensive designer bag for summer, since they won't be using it. Then see what they have to say..

6. Never mix metals in your wardrobe.

This rule basically says that you should never wear gold and silver jewelry together, or god forbid, wear something that has both gold and silver on it! How boring.

Nowadays, it's safe to forget all about it. With all the cute jewelry and metallic accessories out there, it would be a shame to only wear them with some pieces. Metallics are the new neutrals, and you can wear them with whatever you want. Don't be afraid to layer gold, silver and bronze bangles together, or wear silver flats when you have gold earrings on. It's totally up to you and not wrong at all!

Of course, some people have a preference for one type of jewelry over the other. For example, gold doesn't look good on my cool-toned pale skin, so I only wear silver and white gold jewelry. It's okay to have a preference, but don't ever think that you can't wear what you want because it's not "allowed".

7. Never wear tights with open-toed shoes.

Now that tights and peep-toe shoes are both in style, women everywhere are happily ignoring this rule.

That's right, you can totally wear tights with open-toe shoes. Just tuck the seam of the tights under your toes, and make sure it doesn't show. It's a great way to get more mileage out of your wardrobe, because you can wear your peep-toe heels in winter!

Your Thoughts?

What's your opinion on the fashion rules? Do you think they're lame & outdated, or would you never be caught dead in navy blue and black?
