Ruffle or peplum?

The wonderful weather continues, and so does my fascination with color. Unfortunately, I’ve been stuck indoors for the most part, due to classes and homework. Not only do I have senioritis, but I also have week-before-spring-break-itis. Anybody have some great motivational tips? Here’s the breakdown:

Ruffled T: Gap 
Chambray Blouse: Garage sale
Skirt: LOFT 
Flats: Steve Madden via TJ Maxx
Bag: Brahmin (c/o Vogue)
Necklace: Forever 21 

Is it a ruffle? Is it a peplum? I’m not entirely sure, but because peplums are having a fab moment right now, I suppose I’ll call it a peplum. The feminine detail of the ruffle/peplum with the spring-like colors make this a very appropriate outfit for 70-degree sunshine.
