Confused about Dive Rite sizeing

[daani]

I'm buying a drysuit and been looking at Dive Rite 905 exp, the LDC recomended XS-tall for me.
I'm 168cm, 53kg, torso 81cm. Now looking at the divechart they gave me and the suit i got it's something that isn't right.
Even more confusing is when i look at the size chart from Dive Rite http://www.diverite.com/downloads/diverite_64.pdf

Here's a picture with me inside the suit wearing an undergarment.

Are they suppose to look like this? Feels a bit big to me. LDC said it fits OK on me.

and btw I got no experience with drysuits

It looks like 905's I've seen on other folk. It's not a top of the line drysuit, it's not going to fit like a Santi or a DUI. You know what 905 means, right?

IYou know what 905 means, right?

No i don't, what does it mean?

When they first started marketing them, they sold for $905 US.

Now it means that you will stay dry for 9.05 minutes before the first seam leaks.
