Who cares what the guys in over sized chinos and crap shoes think. The fact they mention what you're wearing will mean they have noticed. If another scruff turns up they won't bat an eyelid.
Never dress down because everyone else may do. It leads to a downward spiral and you'll get lazy. Jeans and running shoes await the lazy.
^ all of that. Why shoot for lowest acceptable? Even if jeans were allowed (allowed, not enforced... I've seen some country weddings where jeans were required and even the groom was in jeans), I'd stick to the standard of semi-formal to formal. Dress your best. Take this as an opportunity to put your best foot forward. Would you dress the lowest grade possible for a date? For an interview? Aiming for the lowest mark is a bad habit and one that a person should never impose on their own self.

I think this is safe advice. As long as you don't do the full tux or velvet dinner jacket and black velvet slippers, you're almost certainly at least going to be in the category of less-dressed than the groom. That does NOT mean, however, that you won't look better than he. Especially if he opts for a rented, ill fitting tux and you arrive in a well-thought, fitted outfit.
I don't know what your wardrobe contains, but if I was trying to stay away from the black tie rig (aka, black pants, black jacket, white shirt, black tie), I would don my mid gray pants with a subtle pattern (think sharskin, but a tad softer), crisp white shirt, black velvet jacket (the one piece that says "I'm attending a wedding and wanted to look special for your occassion"), no tie, subtle pocket square, and black shoes (no patent leather, no velvet slippers). Or I may go with the full gray suit, another white shirt, no tie, with walnut strands. Staying with the white shirt may make you more comfortable and not throw you into the "Look at me! I'm trying to steal attention from the wedding" category. Just thoughts.
Oh, and a parting wish, I wish you would be happy enough in whatever you wear so that at some point a smile, or at the very least a neutral expression, paints your face. You should never voluntarily outfit yourself in such a way as to appear vehemently displeased with your attire.
