Tan, simple as that, seriously white looks classy for one hour but trust me you do not want white, youll thank me for telling you this later LOL only joking but I would definitely go for tan
Though I rarely ever do the informal attire because my trainer is very traditional and believes that no matter what level of show (schooling or rated) you should be in formal attire.
So then is it acceptable to wear a black coat with tan pants??
