Filipinas have different taste for men's wear, some wants it simple, ragged, formal, casual, etc.. so the simple way to find out what she wants you to wear is by looking at her pictures, what time of dress she wear. though its not a 100% guarantee that she also like to see them same, but atleast by judging her standard, you made the effort to take the ride.
Some filipinas love to see their date wearing expensive watch or necklace, since it shows status, but some are a bit weary about it since there are snatchers on the streets, that might get you into trouble, so you may take note of this, especially walking on a really crowded public place, but if you are in a mall or beach resort, then wearing those things is not really a big problem.
