Lifesize Fluttershy by CalusariAC. (She’s a plush I commissioned.)
She has a vest underneath her tulle skirt and all of it is removable. Her main outfit is a hoodie that I keep on her most of the time, but I save this outfit for special occasions with her (with my waifu). Her shoes are removable too. It all comes apart piece by piece. The outfit is based on art by Bugplayer.

She is 52 inches long and 17 inches wide at her hips. She has 3D padded heart-hooves, 3D feathered wings, 3D sculpted eyes, heart eyes with extra catchlights, extra long mane and tail, and 3D ears.
