Hi, I am new to Chanel. Just bought 2 PST's in the last week, 1 pink and 1 black. I have a question though. I got the pink PST onsale at boutique, but I thought PST is a classic and never goes on sale?? Are they discontinuing the PST?? So which Chanel styles are considered "classics?" Thanx for any answers for a Chanel Newbie.
