As both a pioneer of horizontal stripes and thereal life published author of new fashion and beauty bible Grace & Style, it seemed only right to ask Grace Helbig to help us sort out some serious style dilemmas we've been having.

Because with so many celebs getting experimental with their looks right now, we seriously need some help deciding which trends we should be getting involved with and which might be best avoided.

Like, are Kimye's matching sheer outfits a style win or a fashion sin? Is Harry Styles' floral suit a big trend or something best left as a pair of your nan's curtains?And what aboutJustin Bieber wearing shorts slung so low that there's a chance they could fall down at any given moment?

Time to find out as Grace reviews a whole load of celeb red carpet style just for you.
