When it comes to baby fashion, the words “gender neutral” are code for “subtle pea green” (nothing to envy about that).Make the case for simple white instead. To wit: Oeuf’s new baby layette.The modern kiddie brand — known for clean lines and eco-conscious design — delivers a selection of baby basics that lives up to its reputation. The entire collection — from beanies to blankets — is made under fair trade conditions in certified organic Peruvian cotton.Items come in sizes 3 to 24 months and include kimono-style onesies and tees, jumpers with and without feet, long- and short-sleeve tees, pants, and ruffled diaper covers. No need to fear baby blowouts; nothing takes a splash of bleach quite like an all-white wardrobe.Perfect for your blank canvas.Available online at oeufnyc.com, $12-$56.Photo: Courtesy of OeufROARDino DayWhat: Get a peek at a 49-million-year-old fossil, meet paleontologists, and munch on snacks.
