We love following Rosie Huntington-Whiteley's casual off-duty looks, but last night at an event in Australia, the model ditched denim for a daring white crop top and fitted maxi skirt from the Calvin Klein Collection Resort 2013 lineup. Strappy silver sandals, a few delicate jewels, and a bold pink lip completed Rosie's pink carpet ensemble. Considering her svelte figure, we're not surprised that Rosie is fearless in putting her midriff on display. And she isn't the only one — many celebs are attempting the crop top trend this Summer. Tell us: are you into Rosie's midriff-baring Calvin Klein Collection ensemble?
