Years after Hill House Home's nap dress went viral, its flattering silhouette and feminine style are still a go‑to formula for fashionable, feel‑good dressing. Now, Old Navy is making its mark on the easy yet chic trend, dropping a puff-sleeved, smocked fit-and-flare that's a dead ringer for something created by the iconic, celeb-loved brand - except this version is 75% off! While countless nap dress dupes have popped up over the years, it's still pretty easy to spot an authentic Hill House Home design.
