    Variability and caveats

    When Aritzia can feel different from the usual sizing tendency

    Cut

    Relaxed cuts can soften a brand that usually runs small, so some pieces may feel closer to true to size.

    Fabric stretch

    Rigid fabrics usually make the sizing tendency show up more clearly because there is less give.

    Styling

    Different collections or sub-lines can use different fit blocks, so styling changes may matter as much as the label size.

    Aritzia's in-house brands (Wilfred, Babaton, TNA) use completely different fit blocks. Wilfred is modelled on an extremely slender European frame and typically runs small.
