Z SUPPLY Fit Guide
Z SUPPLY provides fit descriptions and product measurements on individual product pages. Use these with the body-size chart to understand the intended silhouette.
Fitted / Slim
Designed to sit closer to the body. Prioritize bust for tops and dresses, and waist plus hip for bottoms. Check fabric stretch before sizing down.
Regular Fit
Designed with comfortable everyday room. Choose the size that corresponds with your body measurements unless the product is marked as running small or large.
Relaxed / Boyfriend
Extra width and ease are part of the intended look. Choose your normal chart size to retain the silhouette; size down only if you want a less oversized result.
Between Sizes
Choose the larger size for more coverage, layering or a looser fit. Choose the smaller size for a closer fit only when the fabric and product notes support it.
How to Measure
Bust: With your arms relaxed at your sides, measure around the fullest part of your bust. Keep the tape parallel to the floor.
Underbust: Measure directly below the bust around your ribcage. Keep the tape level and comfortably snug.
Waist: Measure around your natural waistline at its narrowest point. Do not pull the tape tight.
Hip: Stand with your heels together and measure around the fullest part of your hips and seat, approximately 5 inches below the waist.
Inseam: Measure from the top inside of your leg down to the bottom of your ankle bone, or measure a similar garment from crotch seam to hem.
Garment Length: Measure from the shoulder point closest to the neck straight down to the intended hem position.
One-Piece Torso Length: Follow the product’s stated measuring method and compare with its torso-length chart. Torso proportions can affect one-piece fit even when bust, waist and hip match.
Sizing is a guide only. Fit can vary by product, fabric, stretch, wash and intended silhouette. Individual product measurements and fit notes take priority.
