Leo Lin Size Guide: Does Leo Lin Run Small? AU, UK and US Sizes Explained

Leo Lin dresses run true to size. The brand says so on every dress that carries a fit note, and the one piece it flags as running small is the Claire cashmere-blend cardigan, where it tells you to size up. Leo Lin sizes in Australian numbers from AU 6 to AU 18, with the US size printed beside each one. An AU 8 is a UK 8 and a US 4. Coats and capes use letters from XXS to XXL. This guide gives you the conversion, what the brand states about fit on 91 current styles, how each garment family sits on the body, and the one decision that matters most: what to do when you fall between two sizes.

Leo Lin size conversion chart

Leo Lin uses the same number for Australian and UK sizing, and the US size is two steps below it. The brand prints both on its size buttons as “AU 8 (US 4)”, so the chart below is the brand’s own, not a retailer estimate. European sizes are the standard equivalents.

Coveti lists every Leo Lin style on the UK ladder, so the size you pick on our Leo Lin page is the number the brand sews into the label. Coats, capes and a few jackets are cut in letter sizes from XXS to XXL instead, and an AU 8 usually sits at an S.

What Leo Lin says about fit

Leo Lin does not write a fit line on every product page. When it does, the line is short and it is one of two things. We read all 91 Fall 2026 product pages on the brand’s own site and counted.

The fit model is 5 foot 10 and wears an AU 8 on 91 of those pages, with a 5 foot 11 model on 0 styles and a 5 foot 9 model on 0. Read that as a tall model in a small size: a midi that ends mid-calf on her will sit lower on most customers.

Fit by garment

The size number is only half the answer with Leo Lin, because the garments are built so differently. This is how each family sits.

Belted short-sleeve midis

The Bianca, Caroline, Elizabeth and Becca midis share a cut: mandarin collar, fitted waist with a matching belt, straight skirt with side pockets on most. The belt gives you a few centimetres of adjustment at the waist, so this is the most forgiving Leo Lin shape. Your usual size.

Bustier minis and maxis

The Roselle mini, the Rayna and Ava maxis and the Ana midi are strapless with a structured bodice, and several are boned. There is no stretch at all. The ribcage measurement decides the size here, not the hip, and if yours sits between two sizes take the larger one. A dress that is snug across the ribs at 7 pm will not loosen by midnight.

Butterfly-sleeve and flutter-sleeve midis

The Katrina in silk linen and the Aliyah in lace have a high collar, ruffled shoulders, slim sleeves with a frill cuff and an A-line skirt, with a matching belt and a slip included. The silk linen has no give, so size on the bust and let the belt set the waist.

Tweed and vegan suede

The Dusty Pink and Dusty Yellow tweed pieces are a wool-blend with laser-cut appliqué, and they fit like tailoring: size for the shoulders and the bust, because the fabric will not stretch to meet you. The Azure and Chestnut vegan suede pieces, including the Rayna bustier maxi, are softer and true to size.

Gowns

The gowns are the easiest fit in the range. The Agathy velvet gown is cut with a relaxed silhouette, a V-neckline, full lining and an invisible back zip, and the Josephine silk gown is a collared, buttoned shirt gown with side pockets, full lining and a bow belt. Your usual size on both.

Knitwear

The Claire cashmere-blend cardigan is the one piece Leo Lin tells you to size up on. It is cut close, and the brand’s own line is “runs small, we recommend sizing up for a relaxed fit”. If you want it neat over a dress, your usual size still works. If you want it as a layer, go up.

Between two sizes

Three rules cover almost every case. On a bustier style, a tweed piece and a gown you will sit in for hours, take the larger size. On a belted midi, take your usual size and let the belt do the work. On the cardigans, take the larger size unless you want it fitted. Leo Lin does not publish garment measurements in centimetres; its size guide is a body-measurement guide that asks you to measure the bust at its fullest point, the waist at its narrowest and the hip at its widest, with the tape flat and relaxed, so those three numbers are what to have to hand.

Frequently asked questions

Does Leo Lin run small?

Leo Lin dresses do not run small. On the 91 Fall 2026 product pages we read, every dress that carries a fit note says true to size, and the only pieces the brand flags as running small are its Claire cashmere-blend cardigans, where it recommends sizing up for a relaxed fit. Take your usual AU size on a dress, and go up one on the cardigans.

Is Leo Lin true to size?

Yes on the dresses. Leo Lin states true to size on the Caroline midi, the Cleo midi and the Rayna maxi families, and the rest of the range carries no fit warning, which in Leo Lin’s product copy means your usual size. The fitted bustier styles have no stretch, so if your ribcage sits between two sizes, choose the larger one.

What size is a Leo Lin AU 8 in the UK and US?

A Leo Lin AU 8 is a UK 8 and a US 4. The brand prints both on its size buttons, so an AU 10 is a UK 10 and a US 6, and an AU 12 is a UK 12 and a US 8. Coveti lists the same garment on the UK ladder, so the number you select on Coveti is the number on the label.

What size does the Leo Lin model wear?

The Leo Lin fit model is 5 foot 10 (about 178 cm) and wears an AU 8, which is a UK 8 and a US 4. The brand prints that note on most product pages, with a 5 foot 11 model on some styles and a 5 foot 9 model on a few.

Do Leo Lin dresses stretch?

Most do not. The belted cotton midis, the silk-linen butterfly-sleeve dresses, the wool-blend tweed pieces and the boned bustier styles have no give. The vegan suede pieces have a little softness, and the cashmere-blend knits stretch, which is why the brand tells you to size up on the cardigans for a relaxed fit rather than a close one.

What sizes does Leo Lin come in?

Leo Lin cuts its numbered styles from AU 6 to AU 18, which is UK 6 to 18 and US 2 to 14. Coats, capes and some jackets come in letter sizes from XXS to XXL. Coveti lists every numbered style on the UK ladder.
