What to wear over a sleeveless dress to a wedding?

[TheBiscuitStrikesBack]

I’m at a bit of a loss on what to wear over a sleeveless dress to cover shoulders in church but also potentially for a bit of warmth…

Under 40. I don’t want a bolero or anything and not sure a blazer would look right. At a bit of a loss tbh!

Any ideas?

I'd go for a long pretty duster jacket with a bit of flow - something like this, though there will be much cheaper equivalents out there:

I was going to suggest long & flowy, too. I think I prefer potplants's suggestion but, if you'd prefer more of a barely-there look, there's this: https://www.allsaints.com/women/sale-1/misha-mesh-longline-kimono-cardigan/W012KA-3836.html

Allsaints have got this shorter one, too. It might be too boxy for the dress but the colours are good.

I'd just wear a pashmina tbh as can pop on in church then take off.
