Size Guide

SOGNA · Size & fit

Tailor for real life.

For workdays, celebrations and everything in between. Start with your measurements, then find a fit that lets you sit, walk and move comfortably.

Find your starting size

Use your body measurements with the charts below. This is a general guide: fit varies by style, fabric and cut. Where a product has its own measurements or fit notes, follow those first.

These are garment shoulder references, separate from the body measurements above. Lay a well-fitting jacket flat and measure across the back from shoulder seam to shoulder seam. Shoulder construction varies by style; ask us to check the garment you are considering.

Between sizes? Consider the measurement that needs the most room, the fabric's stretch and how you want to move. A slim fit does not automatically mean a smaller size. If unsure, ask our team before ordering.

Measure with confidence

Use a soft tape over light, close-fitting clothing. Stand naturally, breathe normally and keep the tape level, comfortably snug without pulling it tight.

Front-view measuring demonstration using SOGNA models: 1 marks the fullest bust or chest, 2 the natural waist, and 3 the fullest hips. The tape stays level around the body. — Measure around the body at the three numbered points. Model imagery demonstrates tape placement, not actual model measurements or a target body shape.

Bust / chest
Wrap the tape around the fullest part of your bust or chest, passing under your arms and straight across your back.
Natural waist
Measure where your torso naturally bends, usually the narrowest part above your navel. Keep your abdomen relaxed.
Full hip
Stand with your feet together. Measure around the fullest part of your hips and seat, keeping the tape parallel to the floor.

Body size and garment size are different. Clothing needs room for movement. If a product lists flat garment measurements, compare them with a similar piece you already wear comfortably.

Check the fit in real life

A good fit works beyond the mirror. Try your piece with the shoes and layers you plan to wear, then give yourself a little room to live in it.

Sit comfortably

Check the waist, hips and thighs. Buttons and zips should close comfortably without straining.

Walk naturally

Take a few steps. Make sure the hem and shape allow your normal stride.

Reach with ease

Move your arms gently forward. Check for pulling across the back, chest and upper arms.

Choose the intended silhouette of the garment, whether relaxed, tailored or slim, with enough ease for you. Size labels alone cannot tell the whole story.
