I went based off the other reviews and ordered up.  I shouldn't have. The thing was HUGE.  I had to send it back.  If you want to wear this, I'd say order your normal size.  I don't know if it's a crap shoot or they changed things, but if you size up it's gonna swallow you.  I will say that it wasn't see-through when I tried it on, the material is really light and soft. The potential is there.  You just need to get the right size.
