Two additional trends that should be added to your must-try list are

the shirtdress and the drop-waist. 

Aquilano Rimondi and Celine both showed a modern take on the shirtdress for spring. It's an easy day-time look (translation: perfect for a baby or bridal shower, luncheon, etc). Blogger Blair Eadie styled this look with a classic blue & white stripe version of the shirtdress. A lot of the ones we're seeing right now have this faux tie-waist detail that makes it ultra flattering. Add one to your collection pronto. 

Another silhouette I've been seeing pop up amidst my spring shopping is the drop-waist. While it's not an easy look to pull off, I love how Carolina Herrera executed it in a way that is still flattering by showing the natural waist. Delpozo also bought into the trend by showing it in a more avant-garde way.
