Putting attire on invite/details card?

While I understand you don't want others in black, it wouldn't be appropriate to dictate what your guests wear. Black is a very popular color especially for men to wear to a wedding.

Same question was recently asked by another user. I suggest perusing the answers on here:

No, you don't get to tell people what to wear at the reception other than the bridal party.

No, dont' tell people what to wear. Black is super common and wont take away from your H at all. They know who the groom is.

This would be very inappropriate and overbearing. Black is the most common color of formal wear. If my husband and I were invited to a wedding where the invitation asked guests to not dress in black, we would decline.

Thanks everyone. I've been invited to weddings in the past where it was requested to not wear certain colors, wasn't sure about how that works. First time planning a wedding and all....

It’s inappropriate to say anything to guests about what to wear or not wear. They are not props for pictures. The exception is when the venue requires guests to wear black tie attire to enter the venue.
