Caveat emptor is Latin for let the buyer beware.
Beautiful images of H&M's Garden Collection taken by Pascal Gorb; on his blog he states that the line will be out on March 25th. You can view more images here, he also provides links to images of the men's and women's spring collection for H&M in the same post.
I personally think Pascal Gorb has a way of creating a 'rose tinted glasses' image of H&M. When I go into H&M I end up leaving without the desire to waste money, whilst wondering why I always have high hopes for the store.
Answer: Pascal Gorb, though it does sometimes slip my mind his talking about menswear. :/
The centre images are from other designer s/s lines that I assume H&M have taken inspiration from.
