What is sizing like at Jessica Russell Flint?

Jessica Russell Flint comes up generous and runs broadly true to size, with most pieces labelled XS to L — which lands at roughly a UK 8 to a UK 14, and the occasional style stretching to an XL. So if you normally take a 12, you'll almost always be a Medium here. The thing to know before you fall for one of those hand-painted prints is that JRF lives and breathes silk, and silk behaves differently to the cotton-jersey you're used to — which changes how you should size.

I've been buying and styling this little British label for years, and I still think it's one of the most joyful wardrobes-in-a-website going. Founder Jessica hand-illustrates every print in the UK, so you're buying a piece of artwork as much as a garment. But "joyful" and "predictable fit" aren't always the same thing, so here's exactly how it runs.

How Jessica Russell Flint sizing actually fits

Because so much of the range is stretch-silk and pure silk — pyjamas, robes, camis, slip-style dresses — the cut is deliberately fluid and forgiving. Here's what I tell clients:

The silk nightwear and robes run relaxed. The pyjama sets and kimono robes are cut roomy on purpose — they're meant to drape, not cling. Take your usual size; only size down if you specifically want a neater, less billowy line.
Ready-to-wear dresses and skirts are closer to the body. The tailored silk dresses and midi skirts sit nearer true-to-size than the loungewear, so go with your standard number rather than overthinking it.
Camisoles are the one to watch. Silk camis skim the bust and can show every line underneath. If you're fuller-busted, the strappy styles are the place to size up rather than down.
Length is generous. If you're petite (I'm 5'4" and speak from experience), the midi dresses and pyjama trousers often need a small hem or a confident heel.

A quick confession on the "win and a fail" front: my first JRF buy was a silk cami I sized down in, convinced silk would be huge — it clung in all the wrong places and went straight back. My best buy was a Medium pyjama set in their classic celestial print that I've now worn to death and still get asked about. Lesson learned: with JRF, respect the silk and trust your normal size.

Where to shop if you love the JRF look — but want options

If the printed-silk, painterly, slightly-romantic JRF aesthetic is your thing, here's where I'd send you across the price spectrum. These are the brands my own clients reach for when they want that same energy.

High street: the print-and-silk crowd

Hush — the closest high-street match for JRF's boho-luxe mood, with silky camis, easy printed dresses and beautiful loungewear at a far gentler price.
Boden — the British print specialist. If it's the bold, happy pattern you're chasing, Boden does cheerful florals and conversational prints better than almost anyone.
Monsoon — your friend for printed occasion pieces; embellished and embroidered styles that feel special without the designer outlay.
Anthropologie — eclectic, artful prints and a slightly whimsical sensibility; it has actually collaborated with Jessica Russell Flint, so the DNA genuinely overlaps.
The White Company — the go-to for luxe silk and silk-blend nightwear when you want JRF-level fabric quality in a calmer, neutral palette.
Mint Velvet — relaxed, elevated separates and slip dresses with that effortless drape, ideal if you love the fluidity but want a softer colour story.
Whistles — clean, considered prints and silk-mix dresses for the woman who likes pattern but in a more pared-back, modern cut.

Premium: a step up in fabric and finish

Sézane — Parisian-pretty prints, gorgeous silk blouses and dresses, with that same hand-made romance JRF fans adore.
Ganni — playful, slightly off-beat Scandi prints for anyone who wants the maximalism of JRF with a cooler, contemporary edge.
Ghost — the original masters of the fluid bias-cut slip dress; if you want a JRF-style silhouette in a wear-anywhere print, start here.
Brora — British silk and cashmere done beautifully, for that quietly luxurious, made-to-last feeling.

Luxury & designer: the investment pieces

Ralph Lauren — painterly silk dresses and printed blouses with heritage polish; the grown-up, forever-wardrobe version of the JRF print.
By Malene Birger — bold, artful prints and statement silhouettes for the woman who treats getting dressed as a creative act.

Two independents worth knowing (because the big names aren't everything)

I always like to send people somewhere a little off the beaten track, and for JRF lovers these two are uncanny matches:

Klements — a small British label hand-printing surreal, digitally-illustrated designs onto silk. If JRF is your kind of artwork-you-can-wear, Klements is the discovery you'll thank me for.
Beulah London — ethically made, beautifully printed silk dresses with a soft, feminine sensibility and a real conscience behind the label.

The styling takeaway

JRF prints are loud in the best way, so let one piece do the talking. I keep accessories simple — a gold hoop, a neutral sandal, a plain clutch — and let the print be the outfit. And whatever you buy, decide what you want the silk to do: relaxed and floaty (your usual size) or neat and skimming (consider the cut, not just the number). Get that right and you'll wear it for a decade.
