Everywhere we look, another luxury designer is making threads for the little ones. With international brands holding the spotlight, we welcome our newest store from across the pond AlexandAlexa. A Net-a-Porter for kids, AlexandAlexa was started by husband and wife duo, Alex Theophanous and Alexa Till who sought to "source the best contemporary and cool niche brands from all over the world." With virtual shelves stocked with Stella McCartney, Paul Smith, D&G Junior and more, they highlight here their five favorite collections for Spring. New this year to AlexandAlexa are two iconic Italian labels: Missoni and Marni. As for what sells most, "Burberry, Dior, Ralph Lauren and Fendi always sell very well as well as some of our great smaller brands such as Mayoral and Scotch & Soda." SHOP ALEX & ALEXA >
