The availability of clothes depends on the vendor. For example: if you're into corp chic, you'll most likely find what you're looking for at Jinguji in Downtown. Make sure to check various stores - each of them now sells stuff that fits their regular clientele.

This feature has been initially introduced in Patch 1.2, when we adapted vendors' inventory to fit the general location and updated in Patch 1.6, where we went a step further and made sure each store has inventory appropriate to its particular theme.
