"We started seeing more heritage and sportswear brands becoming high fashion when the economy started to turn," said Gregg Andrews, creative director of fashion at Nordstrom.
"People had a real desire for authenticity. There was an emotional attachment to them because of where they are. There is an undeniable familiarity."
Yes, the all-American girl next door promises to be the most important look coming out of this week's fashion festivities. A peek at sketches of local boutique favorites such as Milly by Michelle Smith, Rebecca Taylor, and Nanette Lepore show a bevy of looks that incorporate bold mixes of colors and classic silhouettes.
"My fall 2012 collection is bold and modern," said Smith, who sent a sketch of a sharp Kelly green trench coat over a cobalt-blue shift with - drumroll, please - pockets.
But there is something more: I believe it's signaling that high fashion is beginning to focus on where clothes are made as much as what the clothes look like.
The words made in America are as important as the aesthetic.
"At one time it was a big deal to say that your clothes were made in Europe," said Ann Gitter, owner of the swanky Center City boutique Knit Wit, who said she noticed the shift about seven months ago.
"People make a big deal about things being made here. Shoppers care. They are aware."
The trend is being driven by more than our desire to look like Mad Men's Betty Francis in a pencil skirt or a vintage American flapper a la Boardwalk Empire.
For one thing, American-made clothing has a smaller carbon footprint. So, at a time when we are all going green, it's considered much more environmentally friendly.
And designers trying to break into the business are realizing the costs of sourcing and manufacturing overseas. Why not go to Fourth Street for fabric, find a pattern-maker in South Philly, and have the stuff made in North Philly, like in the old days?
