All three of my boys were dressed up in cute little outfits when they were babies. I just LOVE seeing novelty clothing on them. Let's face it, it's not long before they won't wear anything you pick out for them. Amazon have an impressive selection of Sophie La Girafe/Disney Baby Costumes and they are very reasonably priced too.
As always with any clothing at Amazon, the prices vary greatly depending on what size you are after. Some of the outfits work out cheaper from the Amazon Sellers.
