I think of cute PJ's with this look but the bag is amazing.
I like how the bold lime green dress is separated with a black waist bow and the purple slip slightly visible underneath it.
It's girly, messy, frilly and cute what's there not to like? The model on the left looks like she has a cigarette in her hand which makes the look more like Amy Winehouse.
You may have seen or heard of Betty Jackson in Debenhams because she has a mainline collection and a high street collection (I think).
You can view the rest of the mainline collection here.
I'm in love with this song: Born Ruffians - What to Say.
