Wedding guest dressing has one job: look considered without looking like you tried for three weeks. The dress does most of the work, so start there and keep the rest quiet.
The waist is the whole thing
A midi is really a maxi if the waist sits in the wrong place. Look for a defined waist seam that hits at your narrowest point. Empire lines and drop waists both work, but only if the seam is where your body actually bends.

Necklines that photograph well
Square necks, V necks and halters all show a little collarbone and draw the eye up, which is what you want in a group photo. High necks work when the rest of the outfit stays simple.
Length
Mid calf is the safest midi length, just below the knee is the easiest to walk and dance in. Floor length is lovely and worth the hem if the invitation calls for it.
Fabric and colour
Anything with a little weight hangs better all day than something floaty and thin. Avoid white, cream and anything close to it. Deep colours photograph beautifully, black is fine at almost every wedding now.
Finish it with one thing
A small bag and one statement earring, not a full set. Shoes you can stand in for four hours. The goal is a line that looks intentional, never borrowed.
