It depends. Most "simple" vn girls who don´t speak english well, or not at all, will love you for speaking even only a few words of vietnamese.

Highly attractive, smart girls (who speak english well) may initially be suspicious if you speak vietnamese too well. They´ve seen too many players. Still, if they suspect you of being a player, it´s partly also a compliment. You just need to address their fears.
