Santini - sizing

So, I've put some timber on over the last 12 months .....there....said it. Didn't ride that much but drank more alcohol.

I'm now circa 88 Kilos, 40 inch chest (sorry for the metric/imperial mash up).

Just want to find what kind of jersey sizing I'm looking at (race fit) for Santini these days? It's all a bit confusing. I've usually worn a size xl in Sportful when I was previously circa 78- 80 kilos. I wore a L in Giro Chrono last summer, but they're American so more 'real world' in sizing I figure and not Italian racing whippet size.

Advice welcome, thanks.
