Jane's blouse in her bridesmaid sari is backwards. This could be because she got dressed in the cab by herself (there was no-one around to correct her) and she's also not of Indian origin. The sari being on backwards could be an intentional error by the film-makers.
In the scene where Jane is showing off her 27 dresses, there is a yellow outfit, that they only show the top of, and Kevin holds his hand out infront of her to block out something hes seeing, why do they do that? It shows even later on in the movie that the dress is fine, and does not show anything bad.

He does this because the dress is such a bright shade of yellow; he is pretending that it is hurting his eyes.
Q
Why when Tess met Pedro for the first time she yelled, "HOLA PEDRO"?
A
It is the typical stereotype humour, as in he needed to hear it loud and slow, as in he is Spanish.
