Designer and mother Ariane Goldman has cracked the pregnancy style dilemma with her smart new collection, Hatch. We would love it for the name alone, but the 18 easy pieces chicly cover a blossoming baby bump — and, believe it or not, become a closet staple post-pregnancy. No, really. In fact, you don’t even have to be pregnant to lust after the dreamy strapless gown in palest mint silk, a long tank dress in French nautical stripes, a dinner party dress, airplane dress, caftan and jumper — one chicer than the next, with or without a baby on board — in colors such as sandalwood, fawn, melon, cobalt, navy and black. Hatch donates $5 from each purchase on its Web site to Every Mother Counts, an organization that seeks to improve maternal health worldwide. $78 to $368, at hatchcollection.com.
