I am going on a girls night out Saturday and need to tan. I usually use fake tan but I have more recently found st tropez gradual tan which requires less effort. I want to start applying Wednesday so I am dark enough for Saturday ( it usually takes a few days to build up ) but what do I do about shaving legs ect? Will need to shave Saturday morning but will it totally take off my tan or can I re apply mid afternoon and not look too pale compared to the rest of me? Also do you exfoliate before every application? Any tips would be good...
