Here are two suggestions I sent Nikki - you can click on any image for more info (with the exception of the dress - click here for an alternative option) unless otherwise noted.
For this first (dressier) look, I traded out the red belt for a black version and added a spring colored cardigan (also comes in red).
For this second, more casual option - I again paired the dress with a cardigan (but it would also be cute alone, maybe with some colorful wedges or flats) and a black belt. I gave Nikki the option of wedges or flats, and kept the earrings simple. Click HERE for the coral colored cardigan (perfect for spring!!) - it also comes in a ton of other colors.
