Mimi - You can also just do a google search for 'Ibex Shak' and find lots of outlets (where you can then find other items). I have bought Ibex from Zappos, Sierra Trading Post, Altrec, Backcountry, and from a couple of local stores including TE. I've actually never bought Ibex at REI! Though, I do get most of my Ibex directly from Ibex themselves...

Oh, and definitely check SAC - I've gotten a ton of Icebreaker and Smartwool from them.

Oak - I bet you could wear it. I'm only 5'4" and my hips are definitely as wide as my shoulders (even though I do have a waist) and the shak does not ride up at all. It's also not even slightly flowy - so I don't think it could 'tent' on you. I think because it's a beefier material it stays where it should and looks nice. I actually noted that they seem to be making them a tad roomier than they used to as well. The medium I put on this morning (my newest one in the turquoise color) is larger than my older shaks. Oh, and I definitely put mine in the wash, I just don't put them in the dryer.

Speaking of wool, this is my next wool desire:
