Parents' attire

My mum isn’t keeping to my colour scheme either, ours is pink and grey and my mum is wearing a mustard colour dress!

View quoted message Lol that makes me feel a bit better!

Haha can’t tell them what to do I suppose 😂

I cant tell my mum what to wear, she will do what she wants! Our scheme is pastel rainbow so she has 5 to choose from but guarantee she will pick something outside that range!! Oh well, is not the end of the world I guess, as long as they are comfortable

I think unless you stipulate it, parents, siblings etc that aren’t in the wedding party can wear what they like (within a wider dress code you’ve set). I certainly don’t expect my mom to show up in pink, actually I’d be a bit annoyed if she did (mostly because she’s been telling me she’s wearing navy)
I do expect her to wear something on the smarter side though as our venue is a historic house and we’d like everyone to be more dressed up.

Our colours were blue/purple (OHs kilt colours) and my mother kind-of blended in blue & navy, but only because that was the dress she wanted to wear. MIL was in black & white. It never even occured to me to think about what immediate family would wear - we had a right mix of colours, but I don't think it mattered. You never think about matching/blending colours in any other group photos, so I don't see why wedding pics need to be colour-coordinated either. Let them wear what they want - they'll look so much better if they're in colours & styles they love anyway.
