These were from a Vogue pattern (EDIT: I lied! They were Simplicity. Number 5552 to be exact), which I just spent some time looking for (unsuccessfully). I'll edit it in when I find it.
(edited out the bit where I raved about vogue patterns - oy!). The garment was very pretty too. Here is the finished garment, modelled by my lovely child:
The pants were made on my VS2, the top on the 320k.
I'm now working on a pair (different design - mine are really a Vogue pattern).
