Pattern ideas?

So, I'm tossing around the idea of knitting myself something sexy for my 30th birthday. I've been looking around on Ravelry at stuff I've faved before and new stuff and have found a few ideas...but I wondered...do you guys have any suggestions? I plan to be motivated enough in my going to the gym that I should lose a little weight between now and then, so I want something cute. But then again, it would be fun to go shopping for a cute outfit too. Oh, what to do....
