I have 4 bags from SS 05 and 2 from FW 05 and while it's not a huge difference, I really do find that the Spring/summer ones are softer. Could just be the ones that I got, not sure, but there is a slight difference to me. Maybe I'm just nuts though, lol. HTH
I guess it just depends on the bag. In f/w 05, Balenciaga started introducing the heavily glazed, veiny, crackled leather. My chocolate day and rouge theatre day were like that (not really veiny, but more crackled), but my bordeaux day bag was way softer and silkier than my indigo work or black day from that spring. It was also a lot more thin. The spring 05 leather is noticeably thicker and more matte than fall, and the leather on the bags was more consistent in quality.
I agree...my F/W 05 chocolate and rouge_theatre Work bags have completely different leather. The rouge is more smooth, but thin. The chocolate is "wrinkly" but thick and seems to be able to take a beating.i agree w/ circoit. s/s 05 leather was thicker and spongey soft. f/w 05 was when the leather quality changed...noticeably thinner, some w/ crackled appearance, but not all of the f/w 05 leathers were like this. my 05 gray day is similar to s/s 05 ~ spongey soft.
