i like both of them a lot.
wear with heels and a bag? vague

Was thinking navy suede shoes, navy bag and 'possibly' navy hat/fascination thingy for both.... Not sure which one i prefer yet so thought if I bought navy accessories I could decide later on which dress I prefer

fascinator

no to a fascinator IMO

What about a hat? I do like a hat at a wedding and I think there will be a few, agree on fascinators..

Was thinking this one

Can't think what other colour would work well with both dresses....

Any other thoughts?

One of my friends suggested - same colour shoes for the Emmy dress and a lime green bag/accessories?
