Yes, as I keep telling people, Marks & Spencer are an absolute treasure trove of perfectly decent, reasonably-priced vegan shoes.
These white ones also come in a somewhat less bridal / Essex girl white, but either way are great in an understated cool sort of way.
It’s always good to have stable, functional yet sexy platform heels to go with a nice evening outfit (from the modern to the retro). These even go for less than 30 quid (just). Bargain!
You can get them from the M&S site.
