Choose the slimmer feel
Stay at your usual size for a clean fit, especially if the piece reads as standard cuts.
Choose the roomier feel
Size up only if you want extra ease or prefer this category to feel softer than typical standard cuts.
Variability and caveats
Cut
Structured pieces usually feel smaller first, especially through the shoulders, waist, or hip.
Fabric stretch
Fabric stretch changes how strongly the sizing tendency shows up: more give softens it, less give makes it more obvious.
Styling
Different collections or sub-lines can use different fit blocks, so styling changes may matter as much as the label size.
Nike bottoms cut note: Running tights and training leggings: size up one from your usual. Compression is aggressive.
Nike designs performance apparel with compression as a core engineering spec. Their fit blocks prioritise muscle support and aerodynamic drag reduction, not comfort-first relaxed sizing. Lifestyle sneakers use different lasts to performance runners, this is why shoe sizing differs across sub-lines.
