We have a formal night on our upcoming cruise and my brothers wedding in December so DS (22 months) will need something dressy to wear, hoping to use the same outfit for both. I have khakis and button downs for him but I wanted something a bit dressier. Where have you gotten formal outfits for your DS? Department store? Online? I'm going to check out Ebay and some online consignment shops because it seems like the kind of thing people would use once and then try to resell.
