Finding the Best Brands for Trousers: A Complete Fit & Style Guide

Trousers are one of the most underrated power pieces in your wardrobe. Whether you’re dressing for the office, the weekend, or a night out, finding the perfect pair can elevate your entire look — but with inconsistent sizing, fabric confusion, and hundreds of brands to sift through, the search is anything but simple.

At Tellar.co.uk, we take the guesswork out of shopping for trousers. By comparing your body measurements across 1,500+ brands, we show you exactly which size to buy — in seconds.

This guide explores the best high street and designer brands for trousers, what to expect from their sizing, the fits they’re known for, and how to shop smarter.

Why Trousers Are So Hard to Shop For

Unlike jeans, where waist sizes are often labelled numerically, trousers come in every naming format imaginable — S, M, L; UK 10, EU 38; tailored fit, regular fit, slim leg, wide leg — and not every brand defines these the same way.

➡️ A UK 12 in one store could be a UK 10 or 14 in another

➡️ Your hips may place you in a different size than your waist

➡️ Different cuts (like tapered or wide-leg) can dramatically alter the fit

That’s where Tellar.co.uk

steps in. Instead of navigating guesswork, create a free profile, enter your measurements once, and we’ll match you with the right size in every brand — automatically.

How to Choose the Right Trousers for Your Body Shape

When choosing a trouser brand, consider more than just size:

Body Shape	Best Styles	Avoid
Pear-shaped	Wide-leg, high-waist, flat-front	Tight cigarette trousers
Hourglass	High-waisted, tailored fit	Low-rise, baggy fits
Rectangle	Paperbag waist, pleats, tapered	Flat, shapeless styles
Apple	Elastic waists, straight leg, flowing	Skinny trousers, tight waistbands

Materials Matter: What Your Trousers Are Made From

The fabric composition makes a major difference in comfort and longevity:

Polyester blends: Affordable, easy to care for, but less breathable
Cotton: Comfortable, versatile, prone to wrinkling
Wool: Ideal for winter trousers and workwear, more structured
Linen: Great for summer, but creases easily
Elastane/stretch blends: Allows movement, perfect for fitted trousers

Tip: Always check fabric labels when trying new brands. Tellar stores this info for each item where available.

Blindly ordering your ‘usual’ size — it won’t be consistent across brands

Skimming over the size chart — or worse, not being given one
Assuming your waist is your trouser size — hips often determine fit
Buying without checking return policies — especially for overseas brands
