Once you’ve crossed into your 30s, it’s no longer just about experimenting—it’s about refining. You likely spent your 20s trying on every style under the sun, from questionable festival outfits to budget-friendly trend pieces. But now, with a bit more money in the bank and a deeper understanding of yourself, it’s time to elevate your wardrobe without losing your personality. Here’s how to dress well in your 30s—because growing up doesn’t mean going boring.
1. Refresh and Upgrade Your Wardrobe
By 30, your closet might still be clinging to pieces from years gone by. That hoodie you’ve had since 2015 might hold some good memories, but it’s time to evaluate whether it’s still serving your style. If not, donate it. Start filling your drawers with dependable staples—like high-quality white T-shirts from Sunspel or reliable boxers from Uniqlo. Buy in bulk so you’re always stocked.
Eyewear is another upgrade worth making. One pair no longer cuts it. Now’s the time to start curating a small collection: try black, tortoiseshell, and clear acetate frames. For summer, a lightweight metal option works well.
And when it comes to outerwear, one coat won’t get you through the year. Invest in a few reliable options: two wool coats for winter (a black and a tan one) and a lightweight trench coat for spring and summer. Your older self will thank you when the weather turns.
2. Learn What Suit Works for You
You probably bought your first suit in your 20s—maybe for a job interview or your first wedding invite. Now it’s time to build out that collection. Focus on quality suits in foundational colors like black, grey, and navy. Once those are covered, explore richer textures and patterns like tweed or checks, and fabrics suited to both summer and winter wear.
Remember, a good suit isn’t limited to formal events. Split the pieces up—wear the blazer with chinos or the trousers with a tee. Each suit becomes multiple outfits.
With more weddings and formal events on the calendar in your 30s, it’s smart to invest in a tailored dinner suit. Classic black with a peak lapel is a timeless option, but don’t sleep on a midnight blue number with a shawl collar for a fresh, elegant twist.
3. Dress Smarter When It’s Hot
Back in the day, summer might have meant ditching your shirt and lounging in jeans at the park. But now, your style should rise with the temperature. Hot weather isn’t an excuse to dress down completely.
Start with a pair of swim shorts that double as smart casual wear—brands like Orlebar Brown or Frescobol Carioca get it right. From there, add linen or cotton-blend shirts and trousers to keep you cool while maintaining a polished look. Smart summer shoes like loafers or boat shoes complete the warm-weather wardrobe.
4. Invest in Items That Last
Your 30s are the decade to start buying things that will be with you for the long haul. Focus on wardrobe workhorses: a high-quality trench coat, a beautifully made leather wallet, silver cufflinks, and yes—even a proper umbrella. Go for pieces from reputable brands like London Undercover for both style and durability.
Your shoe collection should also evolve. Diversify with sleek sneakers, Oxfords, and Derbies—shoes that work across a range of settings.
The quality shift isn’t just about individual items. Begin prioritizing premium materials. Merino wool is a great layering fabric for autumn, while cashmere is ideal for staying warm in winter (or even in-flight comfort if you travel frequently). These pieces aren’t just stylish—they’re smart investments.
Even your grooming routine should get an upgrade. Swap those gifted body sprays for a sophisticated signature scent. Try different fragrance families—woody, floral, aquatic, fresh—and match your other grooming products to avoid clashing. The right scent is part of your personal brand now.
5. Buy Less, But Choose Better
Style icon Richard Biedul, 39, shares a crucial tip: think quality, not quantity. “I recently read that the fashion industry is second only to the oil industry in terms of its environmental damage,” he says. “So in your 30s, prioritize mindful consumption. Invest in items made to last.”
That doesn’t mean breaking the bank on designer gear. It means choosing natural fabrics over synthetic, and buying from brands that focus on ethical, sustainable production.
“Move away from fast fashion and seasonal trends,” Biedul advises. “Look for clothes made locally or by global companies that care about responsibility. Keep it simple: buy less, but better.”
6. Trust Yourself
David Byrne once sang, “And you may ask yourself, ‘My God, what have I done?’” If that’s your inner monologue as you stare into the mirror, take a breath. You’ve got this.
You’ve been getting dressed every day for decades. You know what works on you. Trust your instincts. Confidence is what ties it all together—wear your choices like someone who knows exactly who they are.
Your 30s are about refinement, not restriction. You’re still young, and your wardrobe should reflect that. Learn when to go classic and when to play with color. Buy smarter, dress sharper, and most of all—back yourself. Fashion in your 30s is about owning your style, with intention and confidence.
