This isn't a criticism, just curious.
I do a lot of clothes shopping online - all of it in fact.
Anything in green is always sold out faster than any other colour.
Yet I rarely see anyone wearing green!
I've been looking online at a couple of jumpers/ tops online and in every case the green is sold out in every size even though the clothes were only on sale a week ago! (And I don't think it's a case of waiting for the stock to arrive as I've seen the jumpers in store.)
