My daily routine of perusing Net-A-Porter led me to something so simplistically new: the TTD, also known as the top tunic dress. However, I must give credit to Roland Mouret for this genius idea. The TTD is pretty much three pieces in one: a top when tucked into pants, a tunic paired with leggings, and a dress — rad. When shopping for TTDs, make sure to look for sleek shapes and solid colors for maximum versatility and always accessorize with tough elements. Three in one? It doesn't get better than that, folks.
