Take a moment with this guide. A well-fitted garment is the difference between something you wear and something you reach for.
How to Measure
Use a soft tape measure. Measure over a thin shirt, not over a sweater or jacket. Stand naturally — don't suck in or push out. Below is what to measure for each garment type.
-
Chest / Bust: Measure around the fullest part, under the arms, with the tape level around the body.
-
Waist: Measure around your natural waistline (just above the hip bone, where your body bends side to side).
-
Hip: Measure around the fullest part of your hips and seat (typically 8" below the natural waist).
-
Inseam: Measure from the very top of the inner thigh to the desired pant length (usually the ankle bone).
-
Foot length: Stand on a piece of paper, mark the back of the heel and the longest toe, measure the distance.
Tip: the most reliable method of all — measure a similar garment you already own and love, laid flat, and compare it with the garment measurements below.

A Note on Men's Fit
Our pieces are cut with a refined regular fit — not slim, not boxy. Closer to the body than mass-market American sizing, more generous than European slim cuts. If you wear Brunello Cucinelli or Loro Piana, you'll feel at home in your true size. If you wear Bonobos or Untuckit, consider sizing down by one.
Women's Sizing
Tops & Outerwear — Bust Sizing
Our women's sizes follow US standard (numeric 0–14). Pieces are cut with a refined feminine silhouette — not oversized, not body-conscious. Closer to The Row or Khaite than fast fashion.

Bottoms — Pants & Trousers
For pants like The Riviera Comfort Balloon Pants, we use the same US numeric size (0–12). All styles are cut to a single standard length with an inseam of 28" (71 cm) — designed to be worn at the ankle or with a relaxed cuff.

A Note on Jumpsuit Fit
Jumpsuits fit differently than separates because one piece must accommodate your bust, waist, hip, and torso length simultaneously. Our relaxed woven style gives you room through the body without looking oversized; our stretch knit style is designed to follow your shape through the bodice. When in doubt on the woven style, size up — the silhouette stays beautiful with extra room.
Dresses — The Soriano Mesh Maxi Dress
Stretch mesh with a fully lined body — fits true to size. Between sizes? Size up for a softer drape.

A Note on Women's Fit
If between sizes, our recommendation depends on the silhouette: size up for relaxed woven pieces and oversized layers, stay true to size for stretch knit pieces. When in doubt, choose the size that fits your fullest measurement — bust for tops, hip for bottoms.
Footwear
The Soriano Suede Loafer
Our loafers are sized in US Men's. Because there are no laces, the fit is closer than a sneaker. If you wear half sizes, we recommend sizing up by 0.5. If between sizes, size up.

Women's Conversion to US Men's Loafer Sizing
Our loafers are unisex in design. For women looking to size into our men's loafer line, subtract approximately 1.5 sizes from your US Women's size: a Women's 7.5 is roughly a Men's US 6.
