I don't think I have ever seen a RTW 36L suit... Are you a true 36 or more like a 37? Because the alterations from a 38 to a 36 are pretty drastic. I should know, I've had it done when I was a 36, I'm sop happy I'm now a 38. I bet I'm more of a true 37 or maybe 36.5. The 36 is ever so slightly tight, but definitely not bad at all. It fits a hell of a lot better than a 38. Now that I've brushed up on how a suit should fit properly, I'm going to head to Zara to see if there are any suits I like and fit.
