Light and feminine neutrals are a fantastic way to usher in the warm weather. If you gravitate towards simpler, sportier styles like I do, and/or are uncomfortable with overly girlie outfits, then punctuate your look with little feminine touches through ruching or lace detailing (lace is really popular this season). Another method is through feminine accessories - the ruffly Forever21 scarf I'm wearing adds the perfect touch when you can't pull off ruffles on your shirts. Some girls look fabulous with ruffled or ruched shirts but I personally look awful in them. Total disaster. The bonus of accessorizing is that you can always remove a scarf, hat, or cardigan to immediately tone down the look but you can't really remove your shirt. ;)
I usually balance out feminine looks with a bolder shoe and bag. To create an even edgier contrast, I would probably switch out the brown booties, belt, and bag for strong colours like black, turquoise, or red.
