Okay, here’s a more serious argument: her right shoulder is covered by this top, and her left is bare; I just noticed that. In real life, the artist would have chosen one option for both shoulders. Indeed, there is a bit of that.
Now, it seems like we’re just juggling indirect signs and drawing conclusions just to keep the conversation going.

Her left sleeve is lowered, and if the clothing fits quite snugly, then when taking it off, it pulls along what is worn underneath. There is logic in this, and the fold on the top also makes sense.
On the other hand, based on the second sleeve and her pose, one can conclude that the jacket is loose rather than tight.
But on the third hand, the jacket could have caught on the top due to being pressed against the back of the chair. Her pelvis is in a fairly horizontal position. It’s as if she has been sitting for a long time, getting comfortable, and as a result, she has slid down slightly in the chair, and the clothing has wrapped around her shoulder.

В тихой однообразной жизни всегда так бывает: каждый отдельный день бесконечно долог, но месяцы и годы мчатся с непостижимой быстротой.
