Fit and sizing
True to size
A product that fits the way its size label suggests. "Runs small" and "runs large" mean it fits smaller or larger than expected.
Fit notes like "true to size", "runs small, size up" or "runs large, size down" help shoppers choose between two sizes. They're one of the most useful things to add to a size chart.
A fit scale shows the same idea visually, with a marker between "runs small" and "runs large".
