So now to the problems mentioned in the title.
1. Sleeve
The sleeves are quite narrow at the bottom (at Handgelenksaum or what we might call the sonstn), I have these sweaters in size L and you get quite good with my small stature purely / raus. Someone, however, with somewhat stronger wrists problems here will get (can)
2. waist hip (again the hemed hem)
for size L seems to me that almost hem a little tight in front, and is very close to, not cramped but taut ansitzend.
3. V-neck
The cut at the neck is large and it also comes with NEM, say big head, loose inside.
The sweater is indeed 100% cotton, it's not the correct washing hardly any.
All in all I'm very happy with my birthday gift. I can the sweater so "strongly" recommended as this because of its thickness (rather thin) but very warm there. As for the size I can say with my stature 1,84 m tall and about 85kg fits this very well for those who have a few extra kilos or operate power sports I would recommend one size larger. If it does not fit then but one can still return the item.
