Doing a duck face on your dating app is a big no-no, says photographer Charlie Grasso, who helps people look their best for dating websites. First impressions are everything in making the love connection, and Grasso says there are some keys to follow. Aim to appear welcoming, approachable and warm. Try limiting the selfies, and don’t try to be too sexy. “You don't have to try so hard to be sexy because it comes off as desperate and not sexy,” she says. Showing a nice smile is always a plus.
