Also I thought I'd take the opportunity to talk about the fit. Morgan from Crab and Bee asked me whether I had to make any adjustments to the blouse, and given I foolishly left out that vital bit of information when I first posted about the blouse, I thought I'd post about it today.
The answer is no. I didn't make any adjustments, but I did um and aah about what size to cut. Here's where I fell into the sizing:
Bust: 2- 3
Waist: 2 -3
Hips: 1 - 2
Tilly kindly provides the dimensions of the finished blouse with the pattern so that helped a bit and being a person who prefers to wear things a bit looser than tighter I opted for the 3. Now that it's made up I certainly could have made the size 2 but it's not hanging off my shoulders too much - which was my main concern. When I make it again, I might make a 2 but maybe not.
