How to Step Outside the Lines — Inside Out Style

We’ve all heard them—those so-called “fashion rules” that claim to dictate what we should and shouldn’t wear. “Don’t mix black and navy.” “Only wear certain colours at certain ages.” “Avoid horizontal stripes if you’re not a size 8.” But as fashion continues to evolve, so too should our approach to these outdated style limitations. After all, style is personal, and there’s no one-size-fits-all rulebook when it comes to expressing yourself through clothing.

So, when is it okay to step outside the lines and break those long-standing fashion rules? And more importantly, how can you do so in a way that stays true to who you are? Let’s dive into the art of bending the rules without breaking your personal style.

1. “Don’t Mix Black and Navy”  or “Brown and Navy”— Make It Work for You

One of the most outdated fashion rules is the idea that black and navy or brown and navy can’t be worn together. This colour combination is often seen as clashing or unflattering, but in reality, it can create a chic, sophisticated look when styled thoughtfully. Both black and navy are neutral tones, and when paired, they add depth and elegance to an outfit provided that they are colours in your palette (sadly black suits very few people so if you’re 100% sure that your colour properties are Cool, Dark and Bright, which are the colour properties of black, it’s best to avoid it).  Make sure you choose the right navy for your undertone, warm people need a marine or warmer navy that has a hint of green in it, whilst cooler people can wear a wide variety of navy.

The trick to making this combination work is by playing with textures and adding a few contrasting elements. For example, a black tailored blazer over a navy silk blouse paired with black trousers creates a polished look. Adding an accessory in a colour or a lighter tone if you need a higher value contrast can make this look sing.

Style Tip:  You can even add a pop of colour with accessories or shoes to give the outfit a lively boost.

2. “Only Wear Age-Appropriate Clothing” — Redefine What This Means

Perhaps the most restrictive fashion rule is the concept of age-appropriate dressing. This outdated notion suggests that as we age, our clothing should become more conservative and less adventurous. But fashion is all about self-expression, and your style should reflect who you are—not what someone else thinks is “appropriate.”

So, how do you break this rule without feeling like you’re trying too hard? The key is to embrace the elements of fashion that excite you, whether that’s vibrant colours, bold patterns, or daring silhouettes. If a trend or style speaks to you, don’t shy away from it because of your age. Instead, adapt it to your personal taste and lifestyle.

For example, if you love the idea of wearing a bold print but don’t want to wear it head-to-toe, try incorporating it into a statement accessory, like a scarf or handbag. Or if you want to wear something edgy like leather, opt for a classic leather jacket paired with tailored trousers for a balanced, chic look.

Style Tip: Rather than focusing on what’s “age-appropriate,” focus on what makes you feel confident and comfortable. Embrace the styles you love and make them your own.  Check out my post here for more tips.

3. “Don’t Mix Patterns” — Clash with Confidence

The idea that you should never mix patterns has been around for decades, but it’s a rule that’s definitely meant to be broken. When done thoughtfully, mixing patterns can create a look that’s dynamic, bold, and undeniably stylish. The key is to find patterns that complement each other, using a colour palette that’s cohesive.

Start by pairing simpler patterns like stripes with more complex ones like florals or geometric prints. Sticking to a cohesive colour palette will help create harmony between the patterns and keep the look from feeling too chaotic. If you’re new to mixing prints, try starting with a striped top paired with a floral skirt or a polka dot scarf over a plaid coat.

Style Tip: When mixing prints, choose one dominant print and one supporting print. This keeps the look balanced and prevents it from feeling overwhelming.

4. “Horizontal Stripes Aren’t Flattering” — Think Again

Another long-held fashion myth is that horizontal stripes make you look wider and should be avoided unless you’re tall and slim. The truth is, stripes can be flattering on any body type when worn in the right way. In fact, horizontal stripes can add visual interest and even create the illusion of structure, making your outfit more polished and dynamic.

The key is to choose stripes that work for your shape and proportions. For example, thinner stripes tend to be more subtle, and can actually work like a ladder (or vertical) drawing your eye up the body instead of across it. Opt for a striped piece with a tailored fit, like a fine Breton-striped top tucked into high-waisted trousers, or try a striped dress with a belt to define your waist.  Adding a jacket over the tops will further enhance the look.

Style Tip: Don’t be afraid to experiment with stripes in different directions—vertical stripes on trousers and horizontal stripes on a top can create a balanced, flattering look.

5. “Don’t Wear White After Labour Day” — Wear White Year-Round

The old rule about not wearing white after Labour Day is one of American fashion’s most unnecessary restrictions. White can be worn year-round and is one of the most versatile and timeless colours. In cooler months, opt for winter whites in thicker fabrics like wool or cashmere to keep the look seasonally appropriate.  Of course, if you live somewhere that’s covered in snow, white trousers may not be particularly practical, but a cozy white sweater is definitely a great option.

White pieces add a touch of sophistication and freshness to any outfit, making them perfect for layering or standing out as a statement piece. A crisp white blouse under a blazer, a white wool coat, or even white jeans paired with a chunky knit can look effortlessly chic in the cooler months.

6. “Certain Colours Don’t Go Together” — Break the Colour Wheel Rules

Many of us grew up hearing that certain colours don’t belong together, like red and pink or blue and green. But fashion is all about breaking these boundaries. Some of the most striking and creative outfits come from unexpected colour combinations that defy traditions, that trusted “red white and blue” scheme is not your only colour combination option!

For example, pairing warm pink and orange creates a bold, eye-catching look that feels both modern and feminine. Blue and green, when mixed in varying shades, can create a calming, nature-inspired palette that feels fresh and contemporary.  Purple and green are one of my favourite combinations.  Pink and green also work well together and don’t have the same “Christmas” vibe that red and green carry.   Don’t be afraid to play with colour and experiment with pairings that might feel unconventional at first—you may be surprised at how well they work together.

Style Tip: When experimenting with bold colour combinations, keep your accessories simple to let the colours speak for themselves or use the accessories to make those unique colour combinations rather than feeling like you have to do the colour combing only in garments.

7. “Stick to One Style” — Embrace Eclectic Fashion

One of the most liberating fashion rules to break is the idea that you should stick to one style. Whether you’re drawn to classic tailoring, bohemian florals, or edgy streetwear, there’s no reason you can’t mix different styles to create a look that’s uniquely yours. Fashion is fluid, and your wardrobe should reflect your personality, which can have many different facets.

For example, you might pair a tailored blazer with distressed jeans, or mix feminine florals with tough leather boots. The result is a look that’s interesting, personal, and reflective of your style evolution.

Style Tip: Don’t feel pressured to define your style in rigid terms. Embrace the mix of elements that resonate with you and create a look that feels authentic.


Breaking fashion rules doesn’t mean throwing all caution to the wind—it’s about understanding your style, knowing what works for you, and embracing the freedom to express yourself creatively. The most important rule to follow is the one that makes you feel confident, comfortable, and true to yourself.
