The poll also looked at what we noticed when we first met someone – with 57% of us admitting that a smile was one of the first things we noticed. Strangers eyes (29%) and clothing (14%) was also important when making a good first impression.

Clinical Director at elleven, Dr Sameer Patel, said: 'It's very interesting to see Julia Robert's iconic smile has beaten the likes of Kim Kardashian and Jennifer Aniston to the top spot.
