I've had a couple of St Tropez spray tans and found them excellent. Have the spray tan the day before you leave/or your event - then do not wash off that day, even if you're panicking about streaks or face freckles. Shower the next morning and you should see good results! I always exfoliate prior to the spray tan and apply moisturiser to my elbows, knees, back of ankles, top of feet. Hope of some help. Good luck!
