'Arrow' and 'Flash' Star Emily Bett Rickards On the Beach ... Total Felicity Smoak Show

Emily Bett Rickards swapped her hacker gear for a bikini while vacationing with friends in Maui -- and we're sure "Arrow" fans hope she never switches back.

Of course, Emily plays computer expert Felicity Smoak on 2 CW hit shows -- "Arrow" and "The Flash" -- which gives her instant street cred with the Comic-Con set. This bikini gives her cred with the breathing set.

We smell a wardrobe change when she gets back to work.
