I just RSVP'd for a wedding in October online and the bride and groom are requesting that guests wear "garden attire" to their rehearsal dinner. I am sorry, but why are they dictating what to wear to a rehearsal dinner. I think it is one thing to say to not wear jeans, but to actually have a specific dress code seems ridiculous to me especially because I now have to go buy something to wear to this rehearsal dinner because I don't really own anything that adheres to this dress code. Below is I have copied what it says on their website as being acceptable attire for the rehearsal dinner. To me this seems over the top and rather controlling.
Garden Attire: Wear sundresses, floral prints, dress shirts in lighter hues.
