Re wedding shoes - I got mine dyed black and I do wear them for dressy events.
If you really don't think you'd wear them then I'd give them away. Some charity shops have a special wedding section?
Take a pic of them and put with wedding stuff?
Or tbh keep if they mean that much, you don't have to get rid of everything yet :)
I have piled up a massive amount of baby/kids clothes for MIL's refuge, plus some kid equipment, and I've found all the bits for the old p&t, plus instructions if the refuge will take it.
Also went through instructions pile and recycled quite a few for things we don't need.
And found sling instructions for friend's daughter.
Also sorted through boys clothes x 2, got rid of some, checked uniform for going back (have plenty, for now anyway).
Still need to do DD.
And had a massive sort through of shoes - we have tonnes of pairs, too big, too small, etc. Need the DC to try some on but have a huge pile for the refuge.
