When I lived in Pismo it was all shorts and windbreakers, or sweatshirts, and beach sandals. Sneakers in Pismo is a no no, unless you are running on the beach.
Hats are nice...the wind blows much and when it is foggy the hair do's go wacky.
Toiletries and Medical Supplies: face/body/lip moisturizer's
Camping/Beach/Outdoor Gear: boogie board and wet suit...just get out there and do it! :)
Miscellaneous: shark repellent :)
