When a customer takes your fit quiz, their body measurements don't always land perfectly on one size in your size chart. They often fall between two sizes.

That's where Garment Fit kicks in.

Garment Fit is an advanced setting inside the quiz editor that tells SmartSize how a garment actually fits around each body area — bust, waist, and hips. Combined with Priority (how much each measurement matters), these two settings work together to break the tie and pick the right size.

You'll find Garment Fit under Advanced settings in the quiz editor. It has store-level defaults, so most quizzes work out of the box. You only need to customize it when a specific product fits differently than your typical garments.

Each body measurement (Bust, Waist, Hips) has two controls:

Priority determines how much weight a measurement carries when the customer is between sizes.

Garment Fit describes the silhouette and construction around a specific body area. It tells the algorithm what to do when the customer's measurement falls between two sizes in your size chart.

The best way to understand Garment Fit is to see it in action. Here are four dress styles with the same fabric and the same model — the only difference is the cut. Each one needs different settings.

This dress hugs the body from bust to hem. Every area matters equally, and the fit is snug everywhere.

Why: The sheath silhouette is defined by a close fit at every section. Bust and waist use "Structured / fitted" because the customer's measurement must fall within the size chart range or that size is skipped. Hips use "Body-hugging / slim" because when between sizes, a smaller (tighter) size maintains the pencil-skirt line.

This A-line swing dress is loose from the bust down. It barely touches the waist or hips.

Why: The only area that determines the size is the bust — it's the only section where the fabric sits close to the body. Waist and hips are set to "None" because the swing cut flares away from both areas entirely. Bust uses "Relaxed / flowy" because if the customer is between sizes, the larger size keeps the relaxed drape intact.

This dress is fitted through the bust and waist, then flares out at the hips into a full skirt.

Why: The waist is the defining fit point — it's where the bodice meets the skirt, so it gets "High" priority with "Structured / fitted" (the size must fit the waist within range). The bust is fitted too but shares priority as "Normal." Hips get "Low" priority with "Relaxed / flowy" because the flared skirt barely constrains the hips — a larger size just adds more swish.

This empire-waist dress is fitted at the bust, then flows freely from just below the bustline all the way down.

Why: The bust is everything here — it's the only fitted section, so it gets "High" priority with "Structured / fitted" (the customer's bust must fall within the size chart range). Waist and hips are both "None" because the fabric falls straight from the empire seam and never touches either area.

Think of it as a two-step decision:

Together, they let you describe your garment's actual silhouette to the algorithm. The more accurately you set them, the better the recommendation.

You set your store-wide default Garment Fit in Settings. This applies to every quiz automatically.

If a specific product fits differently — like a structured blazer in a store that mostly sells relaxed knitwear — you can override the settings on that quiz only. The override won't affect your other quizzes.

If you set multiple measurements to "High" priority with "Structured / fitted," SmartSize will show a warning. This combination is the strictest possible — it means every body area must fall within the size chart range, and if any one doesn't, the size is eliminated.

This is sometimes correct (e.g., a fully tailored garment), but it can also mean some customers won't receive a recommendation at all. If you see the warning, double-check whether every area truly needs to be that strict.
