I was so excited to finish this top, I have done the thing I don't normally do - the mirror self-portrait!
This is Simplicity 
2599.  This top is also another one of the
 top 10 patterns of 2010.  If you read my blog, you may know that I have set the challenge to make all top 10 outfits (a follower I am!)
This version is my trial version made in a polyester chiffon (yoru?) which cost all of $5 m and seemed perfect for this top.  It is Version B with cap sleeves and vertical ruffles. 
I was concerned when I first tried it on after inserting sleeves that it would be too tight across the shoulders.  I need to get a photo of the back and try wearing it for a day to see how it goes on that score.
  As you can see, it fits Diana very well across the back, but my shoulders are a little broader.
This is a great little top.  It has different cup sizes and I am the b-cup as my high bust is very similar to my full bust (that's those pecs I have worked on so hard ;) )
Even with the cup sizes I found I had to go down a few sizes as the ease is massive in this top.  I am a 34" bust which corresponds to a size 12 but it had something like 5 1/2" ease across the bust - too much for me.  I went down to the size 8, which has 3" ease.  
The other things I did were to leave off the button closure at the back as it slipped on very easily without this, so even though I think it looks cute, I know I will never undo the button.
I also left off the facing and used rayon seam binding to finish the neck edge.  I did as others have done with this too and used a roll-edge hem to finish the ruffle edge.  
The only tip (which I hope will work through the wash!) is that the ruffles are attached with two rows of stitching 3mm apart and the edge is raw.  As this fabric ravels terribly, I made the second row of stitching a narrow zigzag and then trimmed close to the stitching.  I am hoping that it will keep it tidy as well as hold it through washing.  I used my duck-bill scissors to trim the excess fabric.  I love these scissors - you don't want to be cutting a hole in your top at this stage!
Lulu was my sewing helper today and as you can see gave my top the seal of approval...
I am now washing my very expensive piece of silk to make another version of this cute top... Ciao!
