They're not like yoox at all. It's a boutique in Japan that sells all the current seasons, but also has some stuff left from winter. They also seem to sell a used item here and there. The people are very nice. In addition to their store and online shop, they sell a lot of their stuff on eBay for full price in their own little eBay store. They've marked down a bunch of stuff recently too, I guess in correlation with spring sales time. I bought some Dior items from them about a month ago. They ship everything express mail; it arrives in like two days from Japan to the US. Great service. I emailed them from eBay and asked if they'd sell me things from their site that they don't have on eBay even though I can't read Japanese, and they said they'd be happy to. So you could definitely grab whatever Marni from them you want if you just contact through eBay.
I love the way all the pieces fit together, too. It's all like little perfect pieces of a puzzle. But they're all strong by themselves, as well.
