This
is the Carribean Cruise Mix N Match outfit from 2000. It was almost impossible
to find and cost me way over the original retail price, but it's just so
gorgeous! :) 
Rain N Sun Teresa & Barbie (left and right respectively) look perfect and I LOVE the headscarf on Teresa. Barbie is wearing the little green clogs which I think were new for this outfit.
This
is the Tropical Trip Mix N Match outfit, released at the same time as the
Caribbean Cruise. It has the same items of clothing but in a brighter print
and with different shoes. Again, this was pretty difficult to find but is
another of my favourites.
(l-r) Amazing Nails Barbie and Jam N Glam Teresa model this gorgeous outfit. These headscarfs are just perfect for Teresa!
