Yeah, I ordered two alpaca jackets from them on separate occasions. I just emailed the boutique with what I wanted and the size, and Tatjana emailed me back telling me whether they had that item in, and with a price incl. shipping. I then paid them via paypal using the email address she provided. The items were shipped the next day with tracking. It was a really smooth process, however note that they won't subtract VAT (or at least didn't when I ordered early this year). I've read people complaining about the shipping costs but as I live in Australia, I'm used to that anyway, and they are certainly much better than the ridiculous shipping costs that Nomad charges.
Edit: The email address I contacted was: email@example.com
Shrug, I'm an inveterate hoarder/collector so my impulse is oft-times to buy 2-2+ of pieces I really really like. Many pieces from Frozen Waves qualified. Initially I ordered that top in size 6.
Given that that piece is thinner and more delicate feeling I wanted to acquire something else in the fabric. I was hoping they cut a few scarves or something but was told they only had the same top in size 5.
I wasn't sure that it'd fit so I bought primarily to archive. Turns out though a size 5 fits close enough to size 6 in this on me that its just slightly (Not very) more fitted. I archive it nevertheless.
