I went to a colleagues wedding last year and wore a quite distinctive ensemble which is a slightly more dressy version of my usual style (think hippy). I have another wedding this year... another colleague (who I spent most of the time with at the previous wedding) and am considering wearing the exact same thing as it fits really well with the ' 'theme' (nothing overtly costume like but the general idea).
Would this be a faux pas? Some of the guests will be exactly the same as last year and obviously there will be photos etc.
Needless to say, dh will wear the same suit and no one will notice/care.
