I went onto google with miss nicaragua 2001 and got a list of 20 websites. On about number 7 I got three pictures of the coronation of Miss World University. Though the photo seems yellow and the dress is pretty colorless, blue doesn't photograph well (or sometimes at all( and the yellow is probably just wrong film for the fluorescent lighting. I betcha that's your blue dress. Here's the site - darned if I know how to clicky. And going in from google, it'll translate the spanish for you!

Gosh I hope this is it. And I like the dress anyway. Good taste. ET
