The Eight-Section Style (above) is very traditional.
It is fuller than the snap cap, and comes in any fabric, including

waterproof-breathable fabrics. Wool tweed is pictured above.  

The Gatsby Style (left) is a "fuller" eight-section, and includes a snap on visor and a button on the top, if desired.

Both are velcro-adjustable.

The Sport Snap Cap (left) is also a traditional style.
A wool herringbone tweed is shown. The Snap Cap is available in any fabric.
Adjusts with velcro in hat band.  

Prices are the same as above.

Velvet berets (left) are one-of-a-kind and they will fit anyone.  Made from several colors of embossed and non-embossed velvets and handwoven fabrics.   Berets adjust with both elastic and a cordlock.
