Vanson versus Alpinestars vs. AGV suit sizing?

[Garandman]

I believe the Vanson suit I have is size 54. There's plenty of room in it but the torso is kind of short.

Tried an AGV 54 and it was longer and fit better. Where does Alpinestars sizing fit relative to the two?

I've never tried on an AGV, but I did notice that the Vanson's had very short torso's when I tired them. I have an Alpinestars now and it fit much, much better in the torso area than the Vanson.

I have a 54 in a Kobe suit. The torso is on the long side.

(I know they're not on the list, but just a side note...)
