Cherry trees aren’t the only things getting ready to blossom around Washington this spring. Arti Anand, 30, and Komal Kushal Raj, 33, cooked up a new women’s fashion Web sitethat could launch as early as this week. Numari, funded with $75,000 from the two MBAs, allows professional women to customize the size and design of their own dresses, including sleeves and length. The dress prices range between $160 and $285.
