I actually agree with Birkel on this point. There is a little natural crease in the middle of one of my chevre Birkins in the left front piping which even my dad noticed and asked if it was normal. Chevre isn't that rigide so creasing can happen. In retourne it looks more laid back but gets softer. For a 32cm chevre I am thinking perhaps a sellier style will hold it's shape better. I would love it retourne in Togo/clemence or swift because the skin is already softer so a softer look is more natural.in chevre i like the look of sellier better you made a good coice i think its based on the fact that the leather is busy beautifull but it has a noticable natural crease and in sellier the skin-leather is more tensed and so it looks better.
