One of the most noticeable trends on the Spring 2012 RTW Runways was white suits. White alone is a huge trend for Spring (see Louis Vuitton and Chanel, two white heavy collections), but the suits really stood out. As basic and boring as it may sound, there's actually a lot of different looks and attitudes contained in such a simple ensemble.
Come Spring, expect to see lots of white in stores. Separates and dresses will be popular, but consider a white suit. It gives off an instant feel of glamour, but can still be edgy or sweet. It is a classic ensemble that can be dressed around and broken up for years.
