Question about dresses

Wow a lot of posts today.

My question is, why is it assumed a man will rewear the suit he was married in, like the purchase is not a one-time-only deal, but a wedding dress is not to be reworn? Something about it is weird, even if you aren't buying a bridal gown, the idea of wearing the dress again is weird. I know some people do it, but there's the element of surprise - wow, that's your wedding dress? And you're wearing it again?

I mean, why not wear it again? But it feels weird somehow.
