J. Jill garments rarely run small; in fact, the overwhelming consensus among customer reviews and fit profiles suggests that the brand's clothing runs generous and large. Because J. Jill prioritizes relaxed comfort, fluid draping, and effortless wearability, items are cut with extra ease through the bust, waist, and hips. Shoppers who prefer a more tailored, structured fit frequently have to size down, whereas buyers ordering their normal ticket size may find the garments roomier than expected.
