Thinking about Halloween...

We love Halloween at my house.  I've never really decorated for it (although I do have plans for it this year), and I'm not a huge fan of all the creepy/scariness, but I do love candy.  And I do love dressing up.  And Mike lets me dress him up (as long as it's a costume he thinks is cool).  I'm super proud of our costumes from last year:

{I made Mike grow out his mustache for a of couple months.}

Mario, Princess Daisy (the yellow and orange dress wearing, brunette version of Princess Peach), and our little toadstool.  The best part of our costumes is that I made them all the night before (I knew what we were going to be for months, but I procrastinated).  Jokes, that's not the best part.  Mim's hat is the best part.
My first idea for this year was to be Mike, Sully, and Boo from Monsters Inc.  When she has her hair in pigtails, Mim looks just like Boo.  We would probably rent a costume for Mike, and then, if I was pregnant, my tummy was going to be Mike Kwasoski.  So, since I won't be pregnant enough at that point (even if I got pregnant immediately, I would only be 2.5 months along).  I just had to share my plan A though, because I think it's such a good idea.  I know we could still do it, but the pregnant belly as Mike was really my favorite part.  Besides Mim being so adorable.
So my plan B:  Princess Leia, Han Solo, and an ewok.  The costumes should actually be pretty easy, I'm thinking.  A huge white dress that I would cinch around the waist with a belt for me, a black vest for Mike (as well as some knee boots- that'll be the hard part to find for cheapies), and then a snow suit-style outfit for Mim made out of some faux fur.  Add in some blasters made from plumbing parts and spray paint, and I think we'll be good.  Except for all the little details.

{Don't worry, it didn't fall over her face, the hole wasn't big enough.  It's just the angle of the camera.}

So, what do y'all think?  Any better ideas out there?  Anyone know where I could get a size 13 knee high boot?  Is it lame that I'm thinking through our Halloween costumes already?  Anybody need to know how to make a huge mushroom top hat?
