I'm not sure, if my logos are obvious enough. I didn't want them to be gross or too obvious, but since you asked for sexy and playful logo and the event is Wine Affair, there's a double meaning in my logos.
Logo #2 was inspired by this photo:

Of course I can change the shape of the glass or make the double meaning more obvious, but please tell me if you like the whole idea.
