I claim the ornamental design for a hat with an opening to accommodate a hairstyle, as shown and described.
FIG. 1 is a rear perspective view of a hat with an opening to accommodate a hairstyle;
FIG. 2 is a right side elevation view of a hat with an opening to accommodate a hairstyle;
FIG. 3 is a left side elevation view of a hat with an opening to accommodate a hairstyle;
FIG. 4 is a front elevation view of a hat with an opening to accommodate a hairstyle;
FIG. 5 is a rear elevation view of a hat with an opening to accommodate a hairstyle;
FIG. 6 is a top plan view of a hat with an opening to accommodate a hairstyle;
FIG. 7 is a bottom plan view of a hat with an opening to accommodate a hairstyle;
FIG. 8 is a side elevation view of a hat with an opening to accommodate a hairstyle;
FIG. 9 is a rear perspective view of a hat with an opening to accommodate a hairstyle; and,
FIG. 10 is a further rear perspective view of a hat with an opening to accommodate a hairstyle.
The partial human figure shown in broken lines in the drawings illustrates the environment in which the design is used, and assists in showing how the claimed design appears when worn; it forms no part of the claimed design. The broken lines on the hat itself are unclaimed features.
