Is tech outcompeting other forms of signaling, such as clothing expenditures?

For teenage boys, maybe:

Another factor chipping away at teenage retailers may be the shifting priorities among young people. Where clothing was once the key to signaling a teenager’s identity, other items may have become more important and now compete for their dollars.

“Probably the most important thing a teenage boy has is his smartphone,” said Richard Jaffe, an analyst at Stifel Nicolaus. “Second, is probably his sneakers. Third, maybe, we get to his jeans.”

What may trump all of those, Mr. Jaffe said, are gaming systems, especially over the last few months, because Xbox and PlayStation both released new game consoles in 2013. That may have taken a bite out of what teenagers had to spend on clothes.

The Elizabeth A. Harris article, which focuses on declining teen expenditures on retail clothing, is interesting throughout.
