Godtier Rose from SacAnime 2012!
If you have a Walmart near you, their White Stag brand has a pair of canvas sneakers that are really comfortable and very cheap (I got a pair for around $5 for my Terezi cosplay). They don’t seem to have it online though, so I can’t link.

Any simple white canvas sneaker will do though. You just need that and a bottle of pink fabric paint.

Target also has shoes available for around $8. They come in solid white and solid black.
That also! I never actually checked an actual Target (their website yielded few results) so that’s good to know!
