Hi neck top with pockets and a button at the back. This is a cropped / boxy cut.  The sleeves are 3/4 length and are designed to be loose fitting, so you can fit another layer underneath and wear it across the seasons.
 
This vintage fabric is a Sanderson print, that has a bit of a William Morris feel to it.  It's a beautiful quality fabric and has a lovely thickness to it; a bit like a denim.  It's really soft and comfy to wear.
 
This particular piece of fabric was probably a pair of curtains in its previous life.  It is still of excellent quality and pretty flawless but there is a small sign of a tiny snag at the back, which isn't really noticeable but I like to mention it.
