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

Does Princess Polly run small? There is no single brand-wide answer: Princess Polly says apparel fit can differ by fabric and style, and that its size chart is a guide. The U.S. chart runs from size 0 through 20 and is based on bust, waist and hip measurements. For reference, its US14 row lists a 46.5-inch bust, 39.5-inch waist and 51-inch hip; the international conversion chart maps US14 to AU/NZ18 and US20 to AU/NZ24. This matters because the Curve dresses page describes a 16-to-24 range without naming a country, while the U.S. product selectors I checked use US14 through US20. Treat the two labels as different regional scales, not evidence that US24 is available. Princess Polly says its True Fit recommendation uses data from similar shoppers who bought and kept items, and is available on the website but not the app. My read: do not size down automatically; start with the U.S. chart, then check each garment's fabric and cut.

The Khamira Halter Shirred Mini Dress Black Curve combines non-stretch fabric with a shirred waist and adjustable tie neck; its model wears US14/AU18/UK18. Call My Lover Lace Slip Mini Dress Brown Polka Curve is also non-stretch and fully lined, so I would not count on the lace-look name to signal give. Lilienne Cotton Poplin Maxi Dress Red Stripe Curve is partly stretch, with a lined bust, which should feel different from the woven Khamira and Call My Lover. Isakaia Beaded Mini Dress Brown Floral Curve is another lined, non-stretch style with adjustable straps. These four examples do not establish that Princess Polly sizing is small; they show why a single size-up or size-down rule would be sloppy. For fitted woven dresses, compare your fullest measurement against the U.S. chart before ordering, then use the model's size as context rather than a promise of identical fit.

Past Life Fold Over Waistband Pant Brown / Stripe Curve is a wide-leg, mid-rise style in non-stretch linen-cotton, so I would not choose it by the waistband alone. Moses Midi Skirt Multi Curve has a straight hem, mid-rise fit and non-stretch lining; compare hip measurements if you want room to walk rather than a clingy fit. Fawcett High Rise Straight Leg Jeans Light Blue Wash Curve is non-stretch 100% cotton denim, and its model wears US14/AU18/UK18. The product selector I checked offered only US14, so availability can be narrower than the brand chart. Baseline Rib Capri Pants Black Curve is the counterexample: it has good stretch and a ribbed, elasticated waist. My practical rule is to trust stretch as a comfort feature, not permission to ignore the chart; with rigid denim or linen, use your waist and hip measurements and check the listed garment length.

Elaia 3/4 Sleeve Top Black Curve is a ribbed, good-stretch knit made with 95% reclaimed cotton and 5% spandex; Enisa High Neck Long Sleeve Top Black Curve is also good stretch, but its viscose-based blend has a different hand. Deserve You Puff Sleeve Button Front Top Cream Stripe Curve is 100% cotton with no stretch, while Elowenn Long Sleeve Top Black Curve is a lined, non-stretch cotton top with a ruched bust. If you want the least fussy starting point, I would try a stretch knit before a woven button-front cut, then compare the fabric notes rather than buying the same size across both. Princess Polly's guide separately defines standard, tall and petite height bands, but those labels do not guarantee a Curve-specific inseam in every style. The product pages give garment lengths, so check those for your preferred hem. In short, Princess Polly does not prove a universal small fit; the safer answer is chart-first and style-by-style.
