Helllooooooo!
Did I hear my name? lol
I got the discount email, and quickly deleted it as I have too many patterns already waiting to be made up!
Style Arc size charts [in cm and inches] are on a link at the bottom of their site pages.
They do their single size PDFS and the ones where you get your chosen size and one each side of it [ample for most purpose]
They are printed on heavy paper, if you don't go the PDF route
I find the sizes very good, and tend to opt for 16 for stretch fabrics, 18 for woven, as they are a bit narrow on the shoulders for my broad frame.
I've only ever had one PDF file come out incorrectly sized, still no idea why, but I had to take the one skirt in many inches. Only one of gazillions though!
They have some really excellent styles with interesting details, and I think my collection is probably now neck and neck with my Vogues...that Nina cardigan looks great with my art teacher dresses [V9254 coming up on the blog any time now]
