A dash of red can make all the difference, be it in the form of a silky blouse or a new bloom. Especially that blouse pictured above, for which I'd do anything. I love that it's slouchy and carelessly sensual, how it just slips off the shoulder ever so subtly. The poppy-red shade is really just a bonus. Maybe this top by Madewell would do? (There's a zipper on the back that could alter the neckline):
What do you think?
