I spent months banging my head looking for a henley. Most henleys tended towards two extremes:
"¢ A button placket too small and narrow, making the shirt look too "underweary". This is certainly the case of AA.
"¢ A button placket too wide, impractically long, poncey and International Male-ish (many of the higher-end brands including Generra.)
I ended up getting this
Topman henley on sale for !4 shipped. It was in sage greeen, which I liked, because to me, henleys only seem right in earth tones for some reason.
Of course, I posted it in a WAYWT and was summarily dissed.
Proportion-wise, the henleys I've liked the best are RRL and Theory. Both, naturally, are too expensive.
J Crew would have been ideal for me in aesthetics and price if they were more like henley t-shirts rather than henley sweaters. Even Eddie Bauer's henley looked like it might have been nice were it not for the logo.
