Is Katrina a big copycat? Why isn't she wearing original designs in Cannas 2015 then?

Is Katrina Kaif a cheater? Does she have no original ideas? Why else is she wearing all copied designs at Cannes then. She got a thumbs up for the white and black beautiful outfit, mesh black and cropped white top to be precise, when she was talking to the media. This net and lace outfit complemented her red hair, which she is donning for her film Fitoor. But the it turned out to be a copy of singer Alesha Dixon's outfit that she wore in an event, Britain's Got Talent. Then previously the dress that she was wearing, the black net gown on the first day at th red carpet was very similar to what Aishwarya worn two years back at Cannes. In this age of social media, when all types of anomalies go viral, why can't these divas foresee that any blunder on their end will become viral and bring bad name to them. Katrina be smarter next time!
