Like men, sheaths come in all shapes, sizes and colors. For both of these diverse groups of offerings, I am thankful. Getting my mind out of the gutter, a sheath is a must-have for any wardrobe. With an array of shapes, sizes and colors (men), there are so many to choose from (men). This Fall sophistication is key, and a sheath unlocks the door. And finally, you can never have too many to choose from (men!).
