On a Dutch site I found this second-hand dressform for sale,there already was someone who bid on it, but I was lucky my bid was accepted. I was near the seller today, and could pick it up in combination with a business trip.
The dressform is a size 40. On seeing the picture on the internet I already saw that she is too small in general, but that is not so important. I compared the sizes with the BWOF size chart and in bust and hips she is the same as the BWOF size 40. But the waist is 8 cm (more than 3 inches) smaller! My waist is certainly not that small!
But as my back is narrow it's correct in that area and I think I can adapt her to my bust size by putting on a bra. I've seen that done before on several sites. This means that I can use the dressform for blouses and jackets while working on it. The dressform will not be the main fitting instrument for me, just a helpful tool.
Speaking of tools: my serger crashed again! And I've decided to replace it. Too much irritation and time loss because of a badly behaving serger that is 16 years old. I'll be visiting one or two dealers tomorrow, and hopefully have a new serger in the weekend.
