The most important thing to know about Behar is that there are several different lines. The cheapest, which appears in outlets like Saks as their regular stock, is made of quite crappy fabric, shoddy construction, and has some really awful looking buttons. If you inspect the shirt, it will have a tag indicating a retail price of around $60. Stay away from these.
However, Behar makes shirts for NM and the like of much higher quality, with infinitely nicer fabrics and MOP buttons. I agree these are overpriced at retail, but they can show up in outlets and Marshall's as well- you just have to know what to look for. The fit, however, is blouse-like.
