Is it the wrong cut or can I size up?
I finally found a top in the desired style (with a somewhat stretchy fabric) but the smallest size fits very well above the bust. Below and also partly at the waist it’s too tight. I tried to size up, and now the bust is fine, the waist somewhat as well, but the armholes get too big and it doesn’t fit well above the bust at all. In theory I could buy this top, deconstruct it, change the princess seams and use it as a sewing pattern. The question is however if I should abandon this style altogether? I sense that there is something wrong, but I often find that sizing up and down doesn’t always help as my bust here is larger than a size S. I can’t really explain the thing with the area above the bust because it’s not only about size as such, more about that it requires a certain ”tightness” in that area.
I know that the pictures aren’t perfect and I don’t know my ID but I’m 5’4.
If I go by my bust-waist-hips clothes are often made for a larger body (but not a larger bust-waist-hips). Hard to explain.
