To this (I like a challenge) or something vaguely inspired by the beautiful Audrey:
Progress so far. Firstly I used the bodice and neckline of Colette Patterns Chantilly for the top as the circular neckline reminds me of the Hepburn dress:
I made an effort to be a proper seamstress and made a muslin:
I learnt to underline ( thanks to Julia Bobbin) here:
It is almost finished but (even with the muslin) there are some fitting issues I need to address on the bodice and the improvised scallop hem of the underpinning needs sewing.
Next time I attempt a scallop hem I will use this technique (which I discovered on Hettersonjournal Pinterest ). I only discovered it after I had cut my cloth (oops). Almost finished ... just need to remove some of the excess around the bust - I really will feel a sense of achievement when I get to wear this out!
