Sloop Suit Pants Swap?

Hey ya'll, figured I would throw this out there for someone on here. I bought a sloop suit direct from massimo alba, absolutely love the suit. Bought a size 48. The jacket is a little relaxed and ill prob take it in slightly, but the pants, despite me being able to fit in them, are a tad tight on me.

So, I figured i'd see if anyone here has a size 50, but maybe the pants are a little big for them. Let me know would love to do a swap or something.

On a side note, can those pants be let out at all or nah?

Thanks!
