I personally found many things to want to purchase, but if you are speaking from a standpoint of wanting revolutionary new fashion to get excited about, I think that there was a general feeling of transition with the shows. With the move towards 'volume' but the uncertainty of how to realize it, much less sell it to the public, as well as finding a firm new direction that everyone can embrace, it can lead one to feel less than enthralled with the designer offerings. Even in menswear, Hedi's formula is just that, a formula for him. One could feel his need to go against the rules that he himself set a few years back, hence the somewhat controversial collection he showed for Dior Homme.
Also, Tom Ford's exit, no matter how much one may loathe his personal style, has left a void in fashion that none have yet filled, and the level of excitement he brought is gone with him. Gone with Ford is an era of brash sexiness, and we have yet to clearly see what is next on the horizon for fashion. I remember that in most of the 90s, there was so much retro-rehashing that it wasn't until the end of the decade, around 1998, that we suddenly had a new look that was modern and not based on any retro stylings. Perhaps we're going through another such transitional phase again now.
Next season, don't expect too much that's revolutionary from American designers either, since there's a very short time between shows as New York has opted to show a week earlier than its European counterparts. Just last night I already heard grumblings from designers bemoaning the shorter design time that they have to decompress from this recently past season and conceptualize the next. Although hopefully, someone will have a Eureka! moment and surprise us.
