Common materials include felt, polyester, cardstock (paper), faux leather, faux suede, and velvet finishes.
Construction features that maintain the tricorn form include metal snaps around the crown, molded or otherwise stiffened crowns/brims, and brims that are turned up and secured to form the three corners.
Common fit adjustments are an elastic band sewn inside the crown for a snug fit and, on some styles, a hook-and-loop (Velcro) size-adjustment band inside the crown.
Child-focused tricorns often have a stiffened or molded shape, an internal elastic band for a snug fit, faux-fur trim on the brim, and decorative metallic braid.
Most listings include just the hat. A smaller number are sold as sets that add one accessory (for example, a headscarf), so check the specific product listing for included items.
Common decorative details include metallic gold braid or lace-like gold trim, faux-fur edging (sometimes used instead of feathers), decorative lacing, and gold trim on the brim.
Polyester tricorn hats are described as durable and easy-care: resistant to chemicals, stretching, and shrinking; wrinkle- and abrasion-resistant; resistant to mildew; hydrophobic and quick-drying; and easy to wash and dry.
