Aritzia Sizing: Does Aritzia Run Small, Big or True to Size?

Aritzia sizing varies by style, so start with measurements and read the cut rather than trusting your usual number. The women's chart spans 3XS to 2XL and numeric 00 to 16, with denim waist sizes 23 to 32. Its short, regular and tall trouser lengths correspond to inseams of 69 to 72.5 cm, 73 to 76 cm and 77 to 80 cm. That range is more useful than a height guess, especially if the hem is a concern. Wirecutter's five-person trouser test found that the fit note said true to size, yet most testers sized up one and every tester thought the pants ran long. That is a useful warning, not a brand-wide sizing formula. The Original Contour bodysuits describe double-layer fabric for a supportive, body-shaping fit, which will feel closer than a relaxed top. Before ordering, compare waist, hip and inseam measurements with clothes you own, then account for whether you want a close or easy fit. I would size by garment and purpose, not by a label alone.

Rise is the first question with these trousers. New Helix Barrel Pant is low-rise and relaxed, while New Agency Lo-Rise Pant pairs a low waist with an elastic back; Souvenir Pant sits higher and uses a pull-on knit waistband. Archer Satin Pant is a reason to check its exact fit notes instead of assuming satin behaves like a structured trouser. These shapes can sit differently at the waist even when the number on the label matches. Wirecutter's testers still found the trousers long, so measure a pair you like from crotch seam to hem. Decide the rise first, then compare waist and inseam together. If the waistband feels easy in a low-rise style, that may be its intended shape rather than evidence you should size down. A fluid leg can also feel roomier without changing the fit at the waist. Take your measurements before you pick your usual number.

With bodysuits, the right size depends on how close you want the fabric to sit and which neckline you will actually wear. Original Contour Prosperity Crew Bodysuit is a long-sleeve crew with a thong-cut bottom; Original Contour Headway Squareneck Bodysuit adds hidden bra-strap loops. Both use a double layer for a supportive, body-shaping fit. Original Contour Aperitif Bodysuit has a U-neck and built-up collar, also in double-layer fabric. BUTTER Glissade Cami Bodysuit shifts to an adjustable V-neck with ruching and a sweat-wicking second-skin fabric. If compression tends to bother you, be deliberate about the cut, and try each neckline with the bra you plan to wear. The bottom construction matters too: three are thong-cut, which changes the feel under close trousers. I would compare the product fit notes with your torso length and preferred coverage, rather than take a size cue from a model.

Trench sizing is a layering problem as much as a number. The Finch Trench is classic fit and double-breasted in water-repellent cotton twill, with a removable belt and multiple lengths; The Finch Short Trench uses the same fabric family and the product range lists length options. The Esquire Short Trench and The Finch Mid Trench are worth checking against your preferred hem, but I would use their own measurement details rather than assume they match the Finch. Try the intended sweater underneath, close the buttons and reach forward; a coat that binds at the shoulders will stay annoying. Compare sleeve, shoulder and body length, not just the size label. If you want a polished trench over a thin top, a closer fit may work; if you need room for a knit, test the layer before committing. The useful choice is the shape that lets you move and still lands where you want.
