The Truth About Fabric Composition and What’s Actually Worth Investing In?
Growing I didn’t think much about fabric composition. Even as a fashion stylist, I knew certain fabrics were better than others but for the most part, if something looked expensive and I felt like million bucks on a Saturday night out on Clapham High Street, that was enough for me.
But over time, you naturally become more conscious about the way you live.
Particularly in my wardrobe, I noticed how certain pieces held up better than others, how my favourite structured blazer lost its crispness after a few washes, while my cream wool cardigan from Other Stories I purchased years ago still felt luxurious.
As I’ve refined my wardrobe and moved towards more intentional purchases, I’ve started asking: Is polyester really as bad as people say?
And more importantly, is investing in natural fabrics actually worth the money?
If you're focus is on a wardrobe you want to feel elevated, stylish, and long-lasting without wasting money on pieces that fall apart too quickly, keep reading because I’ll be breaking down everything you need to know.
What’s the Big Deal? Polyester vs. Natural Fabrics
At a glance, the difference seems simple:
Polyester is a synthetic fabric made from petroleum-based fibres. It’s affordable, easy to care for and commonly used in fast fashion such as Shein, Pretty Little Thing, even Cos .
Natural fabrics (like cotton, silk, wool, and linen) come from plants or animals and are often considered superior in terms of comfort, breathability, and longevity.
But the real debate isn’t just about composition, it’s about cost vs. value.
Are natural fabrics always better, or are there cases where polyester is actually the smarter buy?
Polyester: When It’s Worth It
There’s a reason polyester dominates the fashion industry.
It’s cheap to produce, versatile and doesn’t wrinkle as easily as natural fabrics. If you’re on a budget but still want a stylish wardrobe, there are some situations where polyester might be the practical choice:
Budget-Friendly: Polyester pieces are significantly cheaper upfront. If you need a trendy piece for a specific event, polyester can be a good short-term option.
Low Maintenance: It doesn’t shrink, wrinkle, or require special care. Unlike silk or wool, you can throw polyester in the wash without worrying about ruining it.
Blends Can Be a Game Changer: Not all polyester is bad. Blends with natural fibers (like polyester-cotton or polyester-wool) can offer a balance between affordability and durability.
Gym and Activewear: Natural fabrics absorb moisture, which can make workout clothes feel heavy and uncomfortable. Polyester’s moisture-wicking properties make it the better choice for leggings, sports bras, and athletic wear.
That said, polyester has its major downsides:
It’s Not Breathable. Ever worn a polyester dress in the summer? The way it traps heat can be unbearable. Natural fabrics like linen and cotton are far more breathable.
It Ages Poorly. Over time, polyester can develop pilling, lose its shape, and start feeling cheap, even if it looks luxurious at first.
It’s Bad for the Environment. Polyester is essentially plastic. It takes decades to break down, and washing it releases microplastics into the ocean. If sustainability is a priority, this is a major drawback.
Natural Fabrics: When They’re Worth the Investment
If you’re moving towards a more luxurious, timeless wardrobe, natural fabrics are where you should be investing.
Yes, they’re often more expensive, but they tend to age beautifully o in the long run you’ve saved.
They Feel Expensive: There’s a reason high-end brands prioritize silk, wool, linen, and organic cotton. These fabrics drape better, feel luxurious against the skin, and instantly elevate an outfit.
They Breathe Better: Unlike polyester, natural fabrics allow air to circulate, keeping you cool in the summer and warm in the winter. That’s why cotton dresses are always a go-to.
They Last Longer (If You Care for Them Right): A high-quality wool coat can last decades. A silk blouse, if properly stored and hand-washed, will look elegant for years.
They’re Better for the Environment: Natural fabrics decompose over time, making them a more sustainable choice than synthetics. Organic cotton, hemp, and linen are particularly eco-friendly.
That said, natural fabrics do also have a few downsides to them too:
Higher Price Point: A 100% wool coat or silk dress can be a significant investment. However, buying second-hand or waiting for sales can help make these pieces more affordable and would be my suggestion of what you could do.
Some Can Be Itchy: Wool, in particular, can feel scratchy against the skin, especially lower-quality versions. Opting for merino wool or cashmere can help avoid this issue.
More Maintenance: Many natural fabrics require dry cleaning or special care, so if convenience is a priority, this might be a drawback.
Where to Invest vs. Where to Save
If you’re building a wardrobe that balances luxury and practicality, here’s how I would recommend approaching your fabric investments:
Where to Invest in Natural Fabrics:
Coats and Blazers → Wool, cashmere, or tweed lasts longer and looks expensive. Try Other Storie, Cos, Mango
Dresses for Special Occasions → Silk or linen holds its shape and drapes beautifully.
Shirts and Top → Cotton and linen are more breathable and elegant.
Sweaters → Cashmere or merino wool is warmer and softer than synthetic knits.
Where It’s Okay to Buy Polyester:
Trendy Statement Pieces → If it’s something you’ll only wear for one season, polyester is fine.
Workwear Blouses → Polyester blends can work if they mimic silk but cost a fraction of the price.
Activewear & Outerwear → Polyester is moisture-wicking and weather-resistant, making it a good choice for gym wear and raincoats.
Finally…
I don’t have any regrets over my fashion choices growing up, I was young and uninformed, but have a brilliant style portfolio to look back on.
At the same time I think it’s impressive Gen Z demand more transparency from brands since brands demand so much money from Gen Z, it’s a very fair trade off.
The key is balance:
For everyday staples, natural fabrics win. They feel better, last longer, and look more luxurious.
For trend-driven, low-maintenance pieces, polyester can be fine. Just be mindful of quality—cheap, flimsy polyester won’t last, but a well-made blend might.
For a budget-friendly luxury wardrobe, focus on second-hand natural fabrics. Thrift stores, vintage shops, and resale platforms like Vestiaire Collective can help you find high-quality fabrics for less.
At the end of the day, luxury isn’t just about how much you spend—it’s about how intentional you are with your purchases. When you invest in quality, you don’t just save money in the long run you also create a wardrobe that makes you feel confident, elegant, and effortlessly put together.
