Come in this Friday, July 10 between 10am-7pm, and have the Del Mar store’s talented hat designers create a one-of-a-kind hat to wear to the races. Whatever your chosen style, color, or theme, your vision will be brought to life. “Bring us your dress for inspiration, give us a theme if you like, or just let our imaginations run wild. You will be race day ready with a chapeau like no other,” says owner Irina Rachow. “We hope to surprise and delight our customers with a new twist on an Opening Day classic. We will even design hats for the guys!” Fairen Del also offers ready-made hats for sale through Opening Day. (858/259-1120, www.fairendel.com)   MASON RICHEY
