In my case, that'd be this one - the original Rainwear Mess Test, featuring Veronica and Eliza, and was our first serious use of rainwear in a shoot. After we'd done it I realise that in fact rainwear fits perfecty with our established lines of girls in boilersuits and other industrial outfits, but until that custom was commissioned I'd not put that particular two and two together.
We've done plenty of other rainwear scenes since, which have sold to varying levels, so it was definitely a good new line to play with, but nothing has matched the sales of the original scene, which is in our top-5 best sellers.
