The pattern is designed for ponte knits and for this test version I used some leftover knit from my stash that is a slightly lighter weight and with more stretch than a ponte which I think affected how this top turned out. You really do need something quite non drapy for that front band to work properly. Still, I like it enough to make another in either a ponte or stretch woven. I think it would also make a great sheath dress by simply extending the lower bodice pieces.
My favourite part of this pattern is how the front wraps over the shoulders to form the sleeve, although I spent a bit of time thinking I must have thrown the sleeve pattern piece away before I realised how it worked! Doh!
Next time I will make the front band as a tube rather than just folding in the edges, I can't see that ever staying in place so on this version I went back and stitched the fold down to the waist seam allowance. Lastly I found I didn't need to use a zip so you could in theory eliminate the centre back seam depending on the stretch of your fabric although it may be useful to add some shaping.
Finally, Clothing Engineer, who makes a lot of Style Arc patterns also just posted this top (also in navy!) and has great tips in case you need to adjust for gaping armholes and neckline. I didn't find this to be an issue at all for me, funnily enough it's the one place the top fits well! For reference I used a size 10.
