I got this in a sz20 (about a size up from what I would normally order), it has zero ease and I wanted it to skim not fit too tightly. The only alterations I had to do was remove about 1cm from the front bodice shoulder seams and lengthen the sleeves and lower the neckline, otherwise this fit is straight out of the packet! It fits very similar to RTW on me, a bit of excess at the lower back and at the front of the armholes but nothing too major.
The grey material is Supplex from a recent fabric.com order, its a surprisingly thick knit and sewed up beautifully, the black is a pique from Lincraft that I've had in my stash for ages. The pique isn't quite stretchy enough so tends to ride up at the neck a bit but the supplex fits really comfortably.
I always thought you needed a specific machine to be able to use a twin needle but on our Brisbane meet-up I learnt that as long as your throat plate will allow it you can use one in any machine (thankyou!). I thought it would be a fiddle around to use but it was so easy. I truly love the finished look and the stretch that it gives, no more popping stitches and its so quick to sew!
I was lucky enough to win a prize from Maria Demark for blogging about the Day to Night drape top and part of it was a packet of twin stretch needles - bonus! She also sent some lovely knit material.
Becky Yoga Pants;
I did make another pair out of the supplex which fit a lot better (the fabric has a lot more stretch), but I can't find them at the moment so I couldn't get any pics! I swear I put them in the wash but for the life of me I can't find them.
