Sundresses are on the casual end, largely sleeveless, and should be comfortable & easy to wear, but classy at the same time; sundresses are not too casual and should look good with strappy sandals or thong flats. This spring, there are a couple of trends that are showing, the biggest one is white. White is the must-have shade for spring dresses. Large print patterns and stripes are popular, too, but are definitely coming in second to the simple white dress. Other trends to look out for are dresses with empire waists and fuller skirts, as well as easy-to-wear shirt dresses, all of which can be very figure flattering.
