I think it’s absolutely lovely, and with coloured accessories would look gorgeous!
If you wore this to my wedding and any other sane person’s I wouldn’t have bat an eyelid.
But - as you can see - there is a bizarre level of preciousness surrounding weddings, and even if the bride didn’t care, you’d have some small-minded guests judging you.
Honestly, this sort of thing reflects so badly on (certain) women.
Can you imagine men kicking up such a fuss about what other men wear?
It’s embarrassing.
