+1 on this. IMO, dressing to the nines can never increase the possibibility of being granted a visa.

Years ago, a relative of mine went to the US embassy for his and his family's visa interviews. Dressed in all their expensive glory, they made sure that they projected themselves in an...affluent manner. Their line of thinking was "If the consul sees that we have money, then they won't think that we would be a flight risk so they would give us a visa." To be sure, the brought all their bank account statements, diplomas, citations, land titles and copies of the scholastic records of their three kids.

They were denied visas.
