I love conversations like these.
Echo excellent point that fast fashion can take what's been seen at a show and make it faster. I have read Zara can take something from idea to shelf in 2 weeks. Whether this harms the designer is debatable. It could harm their RTW business. On the other hand, don't most design houses make their profit from fragrance, cosmetic and most importantly, leather goods? To that point, have you ever noticed that when a blogger high-low styles an outfit, the high end pieces are often shoes and bags. And the other pieces are vintage or fast fashion.
As for trends being all over the place, it seems even more pronounced than 2014. For example, I was looking around for pants hemline trends on Stockholm Street Style (use their tags to edit the many pictures -- their tags are really well organized! Jeans, New York, Milano, capes, etc…). And I saw the expected cropped hemlines with wide leg bottoms and skinny legs. But I also saw what I thought was a frumpy 2" off the ground length on people like Caroline Issa. Then there were floor sweepers/draggers, and some PPLs just 1/4 " off the ground too. It seems like there are 100s of fringe trends with just a few that go big. In a way it's liberating but it's also noisy and makes me want to just stick to a uniform of sorts. As a result I find my style going more classic this year.
Angie -- how could I miss the HK street style thread! Sometimes I miss a few days on YLF. Now off to read it.
