I have a 35 and I'm 5'6. I think as long as you get a leather that is not too rigid aka Epsom or box, the bag will naturally slouch and look smaller. It's the same as carrying the birkin in 35. I hope it helps!
Same here. I have a 35 kelly in clemence and love it. But I did have a 35 in sellier box and sold it to get a retourne box which is the same size but visually looks smaller (and softer). And the 35 box visually looks smaller than the clemence.
Go figure.
