He’s on the stand, saying he took his tux to a dry cleaner the next morning.

If he did, there’s a receipt (and the Tux was still there, at least until he got bailed out)

If he didn’t, then he’s lying on the stand and obviously destroyed the tux.

My assumption is that you can’t get the blood stains out of the shirt. (There is a scene where he tires to, but I believe that’s just in Nicole Kidman’s head?)
