I'm a grad student planning to do a 70.3 in the fall. My budget is somewhat tight but open to spending more for a lot better experience.

Do I need a trisuit? Can I swim in a sports bra + tri shorts, throw on a top for the bike and run? That option seems significantly cheaper for me -- I could get wear a sports bra I already own, get tri shorts to rewear over and over, etc.

Is that advisable for a 70.3 distance? Is there anything here I'm not thinking about? Thanks in advance.
