oh no tara! that really bites, its not like you can rush out and get a backup.
ok, just a brainstorm idea, BUT you know how in mexico they have those lovely mexican style muslin dresses? like with the ruffle/lace border around the top and hem? you could get one of those at the market by the malecon, and use that as your TTD. it would probably work out really cool. you would just need to make sure you have nude colored undies....
i hope it works out for you, either way!
