How to Find Your Perfect Fit at Anne Klein

FASHION HUB — BRAND SIZING GUIDES

By Ella Blake  |  Tellar Fashion Hub

Anne Klein runs true to size on most pieces, but the brand's tailored separates and workwear suiting can come up slightly slim through the waist and hips — so if you're between sizes, sizing up will nearly always give you the cleaner, more polished result the brand is known for. I learned this the slightly painful way when a gorgeous Anne Klein blazer in my usual size sat beautifully on the hanger but was about half an inch too unforgiving across the back. Lesson noted, size adjusted, problem solved.

Who Is Anne Klein? A Quick Brand Primer

If you haven’t shopped Anne Klein before, it’s worth knowing what the brand stands for — because it genuinely informs how the clothes are cut and proportioned. Anne Klein was an American designer who, in the 1970s, essentially invented the concept of mix-and-match women’s workwear. She believed women should dress with the same intelligence and intentionality as men, and her clothes were designed to build a wardrobe around — coordinating separates, sharp tailoring, fluid blouses and classic outerwear that worked harder than anything else in your wardrobe.

Today the brand continues that legacy: this is polished, wearable, grown-up fashion with a strong American sportswear sensibility. Think structured blazers, well-cut trousers, shift dresses and smart knitwear — clothes that transition from the office to dinner without skipping a beat. Not flashy, but deeply reliable. There’s a reason women return to it season after season.

Anne Klein Sizing: The Full Breakdown

Anne Klein uses standard US sizing, which converts relatively neatly to UK sizes with a two-size difference — so a US 8 is broadly a UK 12, a US 10 is a UK 14, and so on. However, the nuances matter, and here’s what I’d flag:

• Blazers and structured jackets: True to size on the shoulders and chest, but can feel snug at the waist. If you have a more pronounced waist-to-hip ratio, consider sizing up and having the waist taken in if needed — much easier than fighting a tight back seam.

• Trousers and suiting: The cut tends to be fairly straight through the leg with a mid-rise. If you carry more volume through the hips and thighs, size up. You can always belt a slightly larger waistband.

• Dresses: Shift and sheath styles run slim — size up if in doubt. Wrap-style and looser cuts are far more forgiving and tend to be truer to size.

• Knitwear: Runs comfortably true to size, sometimes slightly generous. Stick to your usual size unless you prefer a very fitted look, in which case size down.

• Footwear: Anne Klein shoes run true to size for most people, though some pointed court styles benefit from a half size up if you have a wider forefoot.

The Anne Klein Fit Philosophy: Why It Matters

Anne Klein clothes are designed to look tailored and intentional rather than loose or casual — that’s core to the brand’s DNA. What that means in practice is that fit matters more here than at brands where an oversized or relaxed cut can disguise a less-than-perfect size choice. A slightly-too-small Anne Klein blazer will look strained and wrong. The same blazer in the right size looks genuinely expensive and put-together.

The sweet spot with Anne Klein tailoring is a fit that’s clean and close without being restrictive. You should be able to reach forward, sit down and move naturally without the back of a jacket pulling or the thighs of a trouser going taut. If any of those things are happening, go up a size. It will look better, feel better, and last longer.

Building an Anne Klein Wardrobe: Styling Notes

The joy of Anne Klein is its versatility. A few pieces, worn well and in the right size, can carry an entire working wardrobe. Here’s how I’d approach it:

• Invest in a well-fitting blazer first — it’s the workhorse of the whole brand and works over everything from tailored trousers to dark jeans

• Buy separates as a set when possible — Anne Klein coordinates are designed to work together, and a matching trouser-and-blazer in your correct size instantly reads as polished and intentional

• Their shift dresses are classic for a reason — one in navy or black, in the right size, does more work than almost anything else in a smart wardrobe

• Don’t sleep on the knitwear — fine-gauge jumpers in the brand’s neutral palettes layer beautifully under blazers for a smart-casual office look

If You Love Anne Klein, You’ll Also Love These

Anne Klein occupies a brilliant spot in the market — more affordable than pure luxury but considerably more considered than standard high street. If you’re building a wardrobe in a similar direction, these brands are worth having on your radar too:

• Hobbs — the UK’s closest equivalent in terms of polished, intelligent workwear at a sensible price. Their tailoring and occasion dressing is genuinely excellent and the quality-to-cost ratio is hard to beat.

• Phase Eight — particularly strong on dresses and occasion pieces that share Anne Klein’s fluid, feminine sensibility. Their sizing is generous and the fit tends to be very flattering.

• LK Bennett — slightly dressier than Anne Klein but the same smart, confident woman in mind. Brilliant for court shoes and silk blouses that earn their keep in a serious wardrobe.

• Jigsaw — a brilliant choice for classic separates with a slightly more relaxed, British sensibility. Their tailoring and knitwear sit beautifully alongside Anne Klein pieces.

• Ted Baker — for those who want to add a little more print and colour to the polished-workwear formula. Their dresses and occasion separates are consistently well received.

• Reiss — sharp, architectural suiting at a premium high street price. If you love the structured side of Anne Klein, Reiss delivers it with even more tailoring precision.

• Banana Republic — an American cousin with a very similar ethos: smart, versatile, workwear-focused classics that mix-and-match effortlessly. Their tailored pieces are perennially good.

Two independent labels worth discovering:

• Goat Fashion — a British luxury brand beloved by everyone from working professionals to royalty. Their tailored coats, dresses and occasion separates are beautifully constructed and sit in the same considerate, grown-up space as Anne Klein, with a distinctly elevated finish.

• Roksanda — for those who love the structured philosophy of Anne Klein but want something more sculptural and colour-confident. Roksanda’s bold cuts and rich colour palette make her pieces genuinely collectable.
