This number, from H&M is probably the closest I've come so far. I bought it in grey and black and I've worn both a lot. My only gripe with it is the length, I'd just like a bit more of it. Oh and the neckline is a bit high.
I am obsessed with Red Boots at the moment!
Grey Jumper (M/L) - H&M
Black Jeggings (22) - Dorothy Perkins Maternity
Red Boots - M&S
Tell me people - do you have any idea where I can find my perfect jumper?
