Haha, yeah, we're 15 days out. I actually thought DF and I were going to be the only ones who were taking a slightly delayed honeymoon, so I'm glad to see there's a break between you guy's wedding and trip, as well. I'm actually starting to like that we get a little time to settle down before we go on the cruise.
I know I am planning on getting a dress when all the stores start to put out their homecoming outfits for high schoolers. I perused through some yesterday and saw that they weren't horribley priced, but even doing that I will probably border on the not-so-formal side. (I'm probably going to stick with something short)

I just don't feel like packing a lot of fancy stuff. I think, though, with all things clothes, it's a matter of opinion and desire. Some people really want to go all out and enjoy themselves. Normally, I find getting all dolled up fun, but since I'll have spent my wedding like that, I'm taking the formal night a little easier.
I know DF is wearing his military service dress. To me, that's not too formal, but he has worn it on another cruise's formal night, so I suppose it works. He put his foot down right at the beginning and said he wasn't wearing a tux.
I went back and read what I wrote and realized I was really unclear. Sorry if that's confusing.
