I would go nude, you cannot go wrong with nude! They will not clash and you will be able to wear them again.
There are some fab shoes around at the moment, I got a gorgeous pair of peep toe nude patent leather wedges with a strap around the back in Clark’s and they are one of my favourite pairs.
They look lovely, elongate my legs and very importantly, are really comfy. You need to make sure you get a comfy pair for your wedding day….you will be standing alot!!
If you want to bling them up, try shoe clips, they can jazz up plain shoes.
HTH! Best of luck getting everything organised for your big day, you lucky thing, I wish I could have my wedding day again, best day of my life!
