How to get fake tan not streaky?

im a irish dancer and I'm going to nationals so my legs have to be like a bark (ok well not that dark, but pretty dark) color. and every time i put fake tan on it always streaks sooo bad! i have tried putting it on thick, thin, waiting for it to dry before putting on another coat, not waiting for it to dry to put on another coat, putting on one layer one day the next layer the other day. i have tried everything! and it still streaks. i used loreal sublime bronze gel and the dark lotion. also the BE faux tan. and i really dont want a spray tan. what can i do?
