STAYS FREE OF LINT AND PET HAIR!
Size: Large, Style: Tall, Color: Black
Busy bartender with black uniforms and white dogs.
THE STRUGGLE IS REAL!! I wore them all week. Pet hair brushed off with ease. Remained wrinkle free, nice flow and feel. LOVE ALL THE POCKETS!! LOOK GREAT! Haven't had the misfortune of the DREADED BLEACH SPLASH....hoping the fabric blend will prevail! Will order a backup or 3 ;-)
