Costume Dilemma

Should picking out a costume for a three year old be this challenging? Or is EVERYTHING with a three year old challenging? I mean honestly I really dislike this whole trick or treat thing...I really never liked as a child. I never want to force my child to do something especially something that is so borderline to becoming an evil thing, but she wants to dress up. Now I know she will never go trick or treat, which is fine, but she wants to be BUZZ LightYear! Ok, I can deal with that(even though I would choose something different)...YES ERIN, I CAN deal with it, however, I can not deal with paying $60 for this costume, that I have no clue how long it will be on her little body. I have tried many different options for her. We spent 30 minutes in the costume section at red dot boutique, which went from walking up and down the aisles, to her finding an "ugly Buzz costume, and me saying what about this monkey? Then her saying how about this? THIS=A John McCain mask. Then I said how about this dog outfit, she agreed to be a dog, but it had to be a dalmation. We couldn't find a dalmation, so she went back to the hanus BUZZ costume. I just said we will look some more at other stores, we have plently of time. Needless to say, we left the store with her having a meltdown and me totally stressed out! God, please lead me to a dalmation costume....
