It's kind of a cultural component but it is also the weather and the kind of people the weather self selects for. I lived in Del Mar for college a while back and a lot of people who trained for triathlons or liked to surf lived around there. In general people wore less bulky clothes and were more active. Even if that was not your profile at all, you were more likely to be self-conscious about not being healthy.
