I knitted a gauge swatch using 3.6mm needles and it was almost fine.
But, when I reached near the bottom, I found myself using 3.3mm needles.
(I don’t know when and where I mistook needles^^; I may have started the project with 3.3mm needles…)

Thus, the size became smaller than I’d expected.
The width was acceptable (or maybe better, for the intended size S would be a bit bigger for me), but the length seemed insufficient, considering the shrinkage after blocking.
So, I frogged to the waist and added three rounds before and after hip increases.

In the end, I got a nice sweater that really fits my body size.
