And though the collection only launched last week (you probably saw us fawning over it then), several of the pieces have already sold out, which is hardly surprising given that the first two collections between the brands were a huge hit with shoppers - selling out in several pieces and sizes almost immediately.
The Heart Print V-Neck Midi Tea Dress was one of the pieces to sell out, and it's little wonder, given that it is the kind of dress that would work with heels and with trainers or sandals all summer-long.
It's the pop of colour our summer wardrobe needs and means we needn't spend time thinking about accessories, because the dress does all the talking.
The whimsical heart print draws on vintage patterns, while the neckline and elastic waist place it firmly in the present. In short, it's a definite yes from us.
It's crafted from lightweight georgette fabric and has floaty angel sleeves so is super-soft, airy and breathable and will keep you cool on those warmer summer days.
It also features a flattering tie at the back so you can create a svelte silhouette.

Oh, and since we first raved about this piece, other shoppers have had an opportunity to leave some reviews.
"I tried 3 of the new Ghost dresses and even though they were all lovely I couldn’t quite get on with the cut of the necklines and shape of them. I returned them all then saw this red one had come back into stock and decided to give it a try. So happy I did! This is the one! It’s fully lined with a swishy skirt," wrote one shopper.
She added: "I tried both a size 6 and 8 and the size 6 (pictured) is the better fit. The dress is generous on the top so you could size down if you have a small bust like me, otherwise I’d say it’s true to size. I’m 5’4” as well and am pleased with the length. Very happy and so glad I bought it!"
Another commented: "Beautiful dress. I always order a larger size as I am in between 16 to 18 depending on design. The cut is loose which I love though a little bit too long. As I ordered larger size I am returning to shop and will re-order one size down."
