Saint Laurent's Fall '16 runway was the hottest ticket in LA last night. Designer Hedi Slimane kicked things off at the Hollywood Palladium. He previewed menswear and just round one of womenswear, the second of which will be seen in Paris. But our eyes weren't glued to the runway; it was the action in the front row?that had us talking as many a celebrity was spotted at the show. ?From Emma Roberts to Jessica Alba (as beautiful as she?is, something about her overall look didn't gel),?Demi Moore (does the woman ever age?) Lily Collins, and Lady Gaga (whose look we weren't loving, despite her being dressed head-to-toe in YSL), these ladies'made sure all eyes were on them. In terms of beauty, we'll be trying to recreate Collins' amazing smokey eye, Roberts looked perfect and Elle Fanning made good use of some sparkle. Check out the rest of the looks in our gallery above.
