Simply because I'm getting more impressed with Diesel as they are making good washes again...but don't get me wrong...I only bought 3 new pairs, 8x2, 888P and 886B and i'm thinking of selling 8X2 because it's too tight...and i'm getting tired of the diesels I already had for 3/4 years now.
I'm not planning on buying more pairs, those were the only 3 that caught my eye. Others washes are too extreme for me or ugly or if I like them, I don't feel I could wear it with the style I have. I like the Shioner cut though.
But you are right, I went for dior kick for a while....when I had money...but right now i don't feel like putting 300/400€+ for a single pair of jeans..but there is a lot of dior washes I want from previous seasons and stuff but just can't afford it and I don't find nice deals like you ^^.
Another reason I'm picking diesels, is that I needed some light colored jeans for summer ^^ and wanted some change.
