In my experience dress code is much more relaxed, unless of course you work for an organisation that requires you to wear a uniform in which case they provide it.
Most women in office or business situations that I know wear tidy jeans or trousers high heels, smart blouse or top, lots of bling around kneck and dangling from ears and of course the obligatory sun glasses on head!!
Santa cruz women tend to be smarter but then city folk often are
LOL!!!
Lots of guys also wear jeans but often with a shirt and tie, salespeople seem to go for suits more.
