With her husband Jay-Z on tour in Europe, Beyonce has been enjoying vacation time in Paris, where they have been staying, making a splash in the City of Lights in some attention-grabbing fashions.The songstress has been embracing the bright hues of spring by wearing some bold-colored ensembles. After an outing in a multi-colored Carven shirt and popping pink, pleaded-front pants by Vionnet, Beyonce stepped out for dinner with her husband in a bright red jacket paired with curve-hugging leather pants and a black-and-white clutch. But she really turned up the color on Thursday! Exiting her hotel, she had on a bright yellow short-shorts set. The outfit was a little flirty because the top was sheer, so her black bra was visible. She also wore large, round circle shades, which she's sported before back in New York City, and carried the same cow-inspired handbag.While it's easy to just focus on the bold color of her sunny ensemble, the flashiest thing about the look was actually down below on her feet. Beyonce was wearing a pair of Prada's British racing green tail light sandals. Note the flames along each side. (Grease lightning!) The designer shoes, from the label's Spring 2012 collection, were inspired by classic '50s era cars, back when tailfins and polished chrome were all the rage. Celebrities from Victoria Beckham to Katy Perry are owners of shoes in the collection … though we're not sure if they also selected orange toenail polish when they wore theirs like Beyonce did.Beyonce and Jay-Z also brought their six-month old daughter, Blue Ivy, along to Paris. While we'd like to give a detailed account of her presumably designer outfits as well, this is all we saw of her.
