Brides by Glitz Nashville has you covered
I excluded the time we know she was wearing the dress but the shots were so close up you couldn't see it at all, and the rest of the footage has Gillian mostly seated or only seen from the chest up
For the pink, gold, and glittery Valentines inspiration board, I chose a pink glitter dress which might work for a wedding guest for a semi-formal evening wedding if it's in the sort of place (like a restaurant venue) that would be ok for sequins, but if it's a conservative wedding venue like a church, I think it's better to be more traditional and leave these sequins for an engagement party, shower, or even a rehearsal dinner
For a very casual or beach wedding, a lightweight chiffon or a simple cotton-blend dress may suit the relaxed setting better than formal lace, which can read as overly dressy in a barefoot, seaside context
