Most Helpful Guy
Why would there be a change? Seems an odd question.
To specifically answer your question, I'd prefer one that looks good during the day. At night I can always drink. :P
But, more seriously, I think it's a silly question. I love my Girlfriend for a whole host of reasons, and "looks" comes in about 8th. Now, she won't grace the front page of FHM any time soon, but she's also not going to appear on Freeks R Us either. My GF, like most women, is a nice looking average girl. She's healthy, she's not fat nor thin. She looks pretty. She's clearly out of my league and my mates tell me that... all... the... time. And I love her and think she's the best person in the world.
