I wanted to cosplay a pony, but wasn't sure which one to do because I don't have a favourite of the mane six; I like them all equally! I went with Fluttershy because I had a wig and contacts that would work for her.
The dress was purchased; the cutie mark was made out of felt and hand stitched onto the dress.

The shoes were white canvas flats and I painted them with yellow acrylic paint
I bought the basket and bunny plush during Easter from my local dollar store
The flower crown was previously made for another cosplay
