I’m the first owner and have only worn this blouse 1-2 times. Their blouse doesn’t have a crazy amount of stretch however, I can still wear it comfortably at a 84cm bust and 74cm waist. If you have long arms like me these blouse is a blessing. The sleeves are really long and wonderful. My only issue with this blouse is that the neck area is too big for me. For reference my neck circumference is about 33cm. I’d recommend your neck be at least 2-3cm bigger than that unless you don’t mind taking it in to fit better.
