I'd love to know which patterns people have found easy to make adjustments on.
I'll kick off with Butterick 6127 for a cocktail/day dress. It's in the Sew Direct out of print section at the moment. The bust section is in shoulder princess sections and very easy to alter for a full bust. The centre panel makes it a doddle to do final tweaks. Also, the styling has that slimming vertical line. Separate skirt sections are easy to adjust for tums and bums.
NB some people mentioned a size printing fault on the bodice but it is obvious when you look at it which is smaller and larger.
