Why Workwear Still Matters in 2025
Even in a world of remote meetings, hybrid offices, and relaxed dress codes, smart workwear continues to carry weight. Whether you're meeting a client, presenting in-person, or navigating your day-to-day job, how you dress still shapes how you feel—and how others perceive you.
But the modern work wardrobe isn’t about stiff fabrics or outdated cuts. Today, the best suits are:
-
Comfortable enough for 10-hour days
-
Tailored enough to mean business
-
Durable enough to wear for years
-
And—crucially—fit you perfectly
This guide covers the best brands, fabrics, fit strategies, and investment pieces, along with how to use Tellar.co.uk to find your exact size in 1,500+ brands instantly—from Reiss to Arket, COS to The Row.
What Makes a Suit Worth Investing In?
A well-cut blazer or tailored trouser is more than just smart—it’s a wardrobe cornerstone. The best suits:
-
Flatter your natural shape
-
Stay breathable and structured over time
-
Layer effortlessly across seasons
-
Deliver cost-per-wear value
The modern workplace demands functional tailoring—blazers you can move in, trousers with stretch, and dresses that hold shape without feeling tight.
When chosen wisely, workwear doesn’t just get you through the day—it empowers you in it.

Comfortable Staples That Still Look Professional
Smart doesn’t need to mean stiff. These modern tailoring heroes keep you polished and comfortable all day:
✔ Tailored Trousers with Stretch
Ideal for sitting, commuting, or moving between meetings. Look for:
-
Mid-to-high rise
-
Wool elastane or ponte jersey
-
Slight taper or wide leg, depending on your proportions
✔ Relaxed Blazers
Unlined or semi-structured styles deliver shape without rigidity. COS and Massimo Dutti excel here.
✔ Longline Waistcoats
A sleeveless alternative to blazers, especially flattering for petite or hourglass figures.
✔ Fine Knit Layers
Wear silk or merino knits under tailoring—lightweight, smart, and non-restrictive.
Workwear for Different Body Shapes
The Ultimate Clothing Sizing Guide breaks down which cuts suit each shape. Highlights include:
-
Petite: Cropped blazers, high-rise trousers, compact sheath dresses

-
Curvy: Wrap or darted dresses, waisted blazers, stretchy suiting separates
-
Athletic: Strong shoulders, belted waists, peplum shaping for definition
-
Tall: Wide-leg trousers, longline blazers, midi lengths that elongate
Tailoring that matches your proportions = confidence and comfort in equal measure.
