You've probably heard it before but we can't help but say it again - a smile is the key to giving that extra bit of spark so make sure to crack it out a lot on that first date.
Julia says: "When we imagine someone being confident, we imagine them smiling. A smile will tell your date that you like him which will make him more relaxed and make the date easier for both of you.
Smiling makes you look and feel more attractive too making you come across more comfortable in your skin, which is a huge turn on for the opposite sex."
So bare those nashers and he'll be putty in your hands.
