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

Oh Polly sizing is style-specific, though the brand's own product pages often recommend your usual size and sizing up if you fall between sizes. That is the useful answer behind oh polly size chart: the U.S. guide calls itself a reference and points shoppers to each product description for more accurate guidance. It maps XXS to U.S. 00-0 and XXL to U.S. 16, with bust, waist, and hip measurements. Oh Polly says it uses standard UK sizing unless an item description says otherwise, while its U.S. pages display U.S. labels. For a fitted dress, compare all three measurements to the chart first, then read the item's own fit and stretch notes. Modal jersey can give; bonded satin corsetry cannot be treated the same. Model measurements help with length and proportion, but they are not a substitute for your own tape measure. I would rather check the specific cut than assume the same size name fits every neckline, sleeve, and back.

Modal stretch is useful, but it is not a blank check. Viona Modal Mini Dress in Lemon Yellow uses modal jersey with a mesh overlay, and Oh Polly recommends the usual size or sizing up between sizes. Sloane Modal Plunge-Neck Maxi Dress in Wine is a fully lined, body-hugging stretch style marked true to size. The ASOS Modal Sweetheart Lace-Trim A-Line Mini Dress in Chocolate uses stretchy modal jersey, while Modal Square-Neck Bodice Draped-Skirt Midi Dress in Black Polka Dot pairs a modal lining with a different outer blend. These cuts range from long sleeves and a side slit to a square neck and ruched sides, so the material label alone will not tell you where a dress will cling. I would measure bust and waist, then check the product's fit note and the length on the model. If you're between sizes, Viona's brand note recommends going up; do not assume the same rule is printed on every ASOS style.

Structured satin is where I would stop treating the size chart as a shortcut. Nola Satin Draped Mini Dress in Pearl has a bonded satin bodice, princess seams, lace-up back, and chiffon skirt; its page recommends the usual size and going up between sizes. Rixelle Satin Square-Neck Corset Faux-Fur Mini Dress in Wine Red is fully lined satin jersey, marked true to size, and only U.S. sizes 8 and 10 were available when checked. The ASOS Satin Sweetheart Corset Lace-Trim Mini Dress in Leopard has molded cups and underwire, while Mesh Strapless Corset Sweetheart-Cup Draped Mini Dress in Black has detachable straps and a lace-up back. A laced closure can adjust the bodice, but it does not make a dress infinitely forgiving. Check bust, waist, and torso length, then decide whether you want the extra structure. I would not size down because a corset looks sculpted in a studio photograph.

The last four styles show why a neckline or back can change the practical fit. Xynta Satin Jersey Midi Dress in Black is fully lined satin jersey with moderate stretch and a side zip, and its page says true to size. Wyrda Satin Mini Dress in Black is also fully lined and true to size, with molded cups, adjustable straps, side zip, and lace-up back. The ASOS Satin Drape Open-Back Scarf-Detail Mini Dress in Black has a boat neck and open back, while Boat-Neck Cowl-Back Scarf-Detail Mini Dress in Ivory has draping and a cowl back. Before ordering, compare the closure and torso fit with how you want to wear a bra or undergarment; the open backs are not interchangeable with a conventional shoulder strap. On Oh Polly's U.S. site, refunds must be requested within 7 days of delivery, exchanges within 14, and store credit within 28. If you order from ASOS, check its own return terms. My rule is measure first, read the exact style note, then decide while you still have time to return it.
