Beyonce in Blue Roland Mouret Dress

It's official: French designer Roland Mouret is having a pretty great week — and it's only Wednesday. First, he attended the Met Gala arm in arm with bombshell Doutzen Kroes, then Kate Middleton donned his creamy, thigh-slit Fall '09 gown for a dinner in London, and to top it all off, Beyoncé opted to wear his iconic Fall '05 Galaxy dress in a teal blue rendition for the Thriving Child book launch last night. While Beyoncé certainly pulled out all the stops in Givenchy for the Met Gala Monday, her retro curve-hugging choice here proved both subtle and sexy. The cap-sleeve, formfitting silhouette is one that we can really get behind — why? Its nipped waist, square neckline, and altogether glamorously cinematic feel lends itself to more than one body type, highlighting curvier shapes just as easily as it emphasizes the curves we wish we had. We're loving this Mouret moment, and if you're feeling it, too, just shop our editors' picks below to get the look.
