How to Find Your Size in Baukjen

By Ella Blake — fashion stylist  |  Tellar Fashion Hub — always honest, unbiased & unsponsored

Baukjen sizing is true to UK sizing — which is genuinely refreshing — but there's a bit more nuance to it than that, because the brand deliberately cuts different styles with different amounts of ease. Some pieces are intentionally relaxed and floaty; others are structured and close-fitting. Knowing which is which before you click "add to basket" is the difference between a brilliant buy and an expensive return.

"I discovered Baukjen the way most people do — someone wearing the most effortlessly elegant linen dress at a summer lunch, and me immediately asking where it was from. When I finally ordered for myself, I measured up properly beforehand and nailed it first time. The size guide is genuinely one of the better ones out there."

Who Is Baukjen, and Why Does Fit Matter So Much Here?

If you haven't come across Baukjen before, it's a British sustainable womenswear brand founded in 2003, built on the philosophy that clothing should be beautiful, long-lasting, and made responsibly. It's B Corp certified, uses ethical manufacturing, and designs pieces that are intentionally grown-up and wearable — think elegant midi dresses, beautifully cut trousers, relaxed knitwear, and smart-casual separates that actually suit real women's bodies.

Because the brand deliberately plays with silhouette — relaxed here, nipped in there — fit guidance matters more than with a brand that sticks to one consistent cut across everything. A Baukjen dress that's meant to skim the body feels very different from their oversized weekend knits, and the sizing logic shifts slightly with each.

Baukjen Size Range and How It Maps to UK Sizing

Baukjen runs sizes 6 through to 18 in most styles, with a number of pieces also available in a petite range — a detail I think is genuinely underrated and worth flagging. Here's a general guide to how their sizing maps:

• Size 6–8 (XS): Bust 31–33", Waist 23–25", Hip 33–35"

• Size 10 (S): Bust 34–35", Waist 26–27", Hip 36–37"

• Size 12 (M): Bust 36–37", Waist 28–29", Hip 38–39"

• Size 14 (L): Bust 38–39", Waist 30–31", Hip 40–41"

• Size 16–18 (XL–XXL): Bust 40–43", Waist 32–35", Hip 42–45"

The key thing: these sizes reflect the garment's designed measurements, not necessarily the finished garment measurement. A relaxed-fit piece will have additional ease built in on top of these numbers, meaning it will look and feel bigger on. Always read the product description for fit notes — they're unusually honest about intended silhouette.

The Styles That Run Relaxed (and What to Do About It)

Baukjen's knitwear, weekend shirts, and linen separates are cut with considerable ease — this is intentional and part of the aesthetic, but if you're petite or prefer a more fitted look, it's worth sizing down by one. Their relaxed-fit trousers in particular have a generous cut through the hip and thigh that can overwhelm a smaller frame.

Conversely, their tailored workwear pieces — structured blazers, fitted ponte trousers, some of their occasion dresses — sit much closer to the body and run more true to size. For anything described as "tailored," "fitted," or "slim," stick to your standard UK size. If you're between sizes and have a fuller bust, size up and consider alterations at the waist if needed.

Petite and Tall Options at Baukjen

This is one of the things I genuinely admire about the brand — they take petite sizing seriously rather than just hemming standard pieces shorter. The petite range is actually cut with a shorter body length, adjusted sleeve proportions, and a slightly narrowed shoulder, not just a shorter hem. If you're under 5'4", it's absolutely worth shopping the petite range first.

There isn't a dedicated tall range as of now, but the midi and maxi lengths tend to work beautifully on taller frames without looking cropped — another detail that feels considered rather than accidental.

Tips for Shopping Baukjen Online

• Always measure before ordering — their online size guide includes garment measurements alongside body measurements, which is far more useful than a standard chart

• Read the fabric notes: Baukjen's TENCEL and linen pieces tend to have the most ease; their ponte and jersey pieces are more structured and fitted

• Check the fit model height: They often note what height and size the model is wearing — genuinely helpful for gauging length on a dress or trouser

• Petite shoppers: Always try the petite range before defaulting to a standard size — the proportions are properly adjusted

• Sale pieces: Baukjen's sale is excellent quality, but returns are sometimes limited — measure up even more carefully before buying reduced pieces

High Street Brands with a Similar Aesthetic

Baukjen sits in that lovely grown-up, quietly elegant space that not every brand occupies — but there are some brilliant alternatives when the price point isn't quite right, or you want to build out the look for less:

• Whistles — the closest high street match in terms of elevated minimalism and wearable cuts; their trousers especially (consistently well-reviewed for fit and fabric quality)

• Jigsaw — beautifully made, understated pieces with a similar British sensibility; their knitwear is particularly strong

• The White Company — for the linen, relaxed-fit side of the Baukjen wardrobe; excellent for holiday and weekend dressing

• Me&Em — smart-casual pieces with superb fit and quality; their trousers have a very similar tailored-but-wearable cut to Baukjen's workwear line

• Hush — perfect for the cosy, weekend knitwear end of the Baukjen spectrum; lovely fabrics and very honest sizing

• Boden — brilliant colour and print; a bit more playful than Baukjen but similarly well-made and size-inclusive

• Mint Velvet — excellent for the occasion-wear and smart-casual pieces; their sizing tends to be generous and forgiving, which is a nice contrast if Baukjen's structure feels snug

• Phase Eight — particularly good for occasion dressing with a similar grown-up, flattering silhouette approach

For independent alternatives, I'd point you towards Albaray — a relatively new British sustainable brand with a strikingly similar aesthetic to Baukjen (relaxed, elegant, ethical) and excellent sizing consistency — and Birdsong, a London-based ethical brand making beautifully considered pieces in sizes 6–26, with a transparency about their production that's second to none.
