Can You Actually Tell the Difference Between Designer & High Street Workwear?

TELLAR FASHION HUB — STYLE ADVICE

By the Tellar Style Team | February 2026

Honestly? Sometimes yes, sometimes absolutely not — and knowing which is which is one of the most useful skills you can develop as a working woman with a wardrobe to maintain and a budget to respect. The short answer is that a well-chosen high street piece worn with confidence can hold its own next to something that cost five times as much. But there are specific categories where the difference is real, visible, and worth paying for.

I've spent years dressing both myself and clients for professional environments across a wide range of budgets — from graduate-scheme starter wardrobes to City lawyer upgrade edits — and I can tell you from experience that the gap between high street and designer workwear is not as wide as it used to be. The high street has become genuinely impressive in certain areas. In others, though, you really do get what you pay for, and cutting corners will show.

Where the High Street Genuinely Holds Its Own

Let's start with the good news. There are several workwear categories where a canny high street buy is virtually indistinguishable from its designer counterpart — provided you know where to look.

Tailored trousers — Cos vs designer: This is one of the clearest wins for the high street. COS's tailored wide-leg and straight-leg trousers in technical fabrics genuinely rival much more expensive options. The cut is clean, the fabric holds its shape, and unless someone is running their hands along the seam (which would be odd in a meeting), you would not know. At under £100, they represent extraordinary value.
Blazers — Zara and Mango punch above their weight: Both brands have become known for structured blazers that photograph and wear beautifully. The structured shoulder, clean lapel, and overall silhouette of a well-cut Zara or Mango blazer can look genuinely polished in a work context. The lining and button quality are where you'll feel the difference, but you likely won't see it from across a boardroom table.
Knitwear — M&S and Next deserve real credit: Fine-knit jumpers and cardigans in neutral colours are an area where mid-market retailers have genuinely closed the gap. An M&S fine-knit merino in camel or navy is difficult to distinguish at a glance from a version costing three times as much. The hand feel may differ slightly, but the visual result is comparable.
Shift dresses — Hobbs and Phase Eight: These two British brands occupy a premium high street space that produces work dresses that look genuinely expensive. Their ponte and structured crepe fabrics, clean seaming, and considered silhouettes are routinely mistaken for designer by people who don't know the labels. This is arguably the sweet spot of the entire workwear market.

Where You Really Can Tell the Difference

Now for the honest part. There are certain workwear pieces where the designer or premium price tag is reflected in something tangible — and where cutting corners will quietly undermine an otherwise polished look.

A properly tailored suit: The moment someone sits down, moves, or takes off their jacket, the quality of tailoring becomes apparent. A designer or made-to-measure suit — from a brand like Max Mara, Totême, or a tailoring specialist — has a structured canvas, hand-finished details, and a cut that accounts for movement. A fast-fashion suit collapses slightly the moment you sit, and the fabric often loses its shape by midday.
Silk and luxury fabrics: A real silk blouse from Equipment or L'Agence has a weight, lustre, and drape that polyester satin simply cannot replicate. In person, in good lighting, the difference is obvious to anyone who works in a professional environment. This is an area where a splurge genuinely pays off — a quality silk blouse worn regularly across years works out cheaper per wear than multiple synthetic versions.
Leather accessories — bags and shoes: Nothing dates or cheapens an outfit faster than low-quality leather. A structured work bag and clean leather shoes in genuine leather age beautifully; synthetic alternatives scuff, peel, and look tired quickly. This is one of the clearest visible differences between an expensive outfit and an inexpensive one, even when the clothes themselves are high street.
Trench coats: The cut, weight, and hardware of a well-made trench coat are immediately apparent. A Reiss or Whistles trench sits at an excellent mid-point; a Burberry trench is in a different league entirely — but the Reiss version looks significantly better than the fast-fashion alternative at £100 less.

The Smart Approach: Where to Spend and Where to Save

This is the real skill of building a workwear wardrobe. The most well-dressed women I've styled — at every budget level — all operate on the same principle: spend on the pieces that are seen and touched up close, save on everything else.

Spend more on: a quality blazer or suit jacket, leather shoes and a work bag, a silk or quality-fabric blouse, and your outer coat. These are the pieces people notice and remember.
Save intelligently on: trousers and skirts in jersey or ponte (the high street is brilliant here — Jigsaw, Banana Republic, Massimo Dutti), basic knitwear, and layering pieces.
Mid-market premium is often the sweet spot: Brands like Reiss, LK Bennett, Hobbs, Me&Em and Ted Baker occupy a space where the quality is genuinely good and the price is justifiable for work pieces you'll wear dozens of times. They often get overlooked in the designer-vs-high-street conversation, but they represent some of the best value in professional dressing.

The Brands That Blur the Line Most Successfully

If I had to pick the high street and premium brands that most convincingly read as expensive in a professional context, these would be my picks:

Cos — clean lines, quality technical fabrics, and a minimalist aesthetic that photographs and wears like something twice the price.
Reiss — consistently well-tailored pieces that hold their own in even high-end professional environments. Their blazers and dresses in particular.
LK Bennett — beloved by professionals for good reason. Their court shoes and structured dresses are polished, enduring, and quietly expensive-looking.
Massimo Dutti — frequently described as "the poor man's Max Mara," which undersells it. Genuinely beautiful fabrics at mid-market prices; their outerwear especially.
Claudie Pierlot — a French brand sitting just above the high street that delivers elevated, Parisian-influenced workwear with real quality. Blazers and dresses particularly stand out.
Hobbs — one of the most underrated workwear brands on the UK high street. Consistently smart, consistently well-made, and consistently mistaken for something more expensive.

Two Independent Brands Worth Adding to Your Radar

Ro&Zo — a small, thoughtful British brand producing incredibly well-cut workwear separates and dresses in quality fabrics. Their tailoring punches significantly above its price point; colleagues will ask where your blazer is from, and the answer will surprise them.
Wyse London — a premium independent brand known for beautifully made knitwear, silk tops, and elevated basics. Their pieces read as luxury without the luxury price tag, and they're an excellent source for the kind of quietly expensive-looking work blouse that's otherwise hard to find.

The honest verdict: The high street has never been better for workwear — but fabric quality, tailoring construction, and leather goods are areas where spending more is still genuinely worth it. The key is knowing the difference, choosing your splurges wisely, and building the rest with smart high street picks from brands that consistently over-deliver.

Nail Your Size Across Every Brand — Free, Instant & Accurate

Here's the thing about investing in quality workwear: it only pays off if it actually fits. And with sizing varying so dramatically between brands — a 12 in Hobbs is not a 12 in Reiss is not a 12 in Cos — ordering online or shopping across multiple stores becomes an expensive and exhausting guessing game.
