If you're going to get a spray on tan, Botanical Tans is the way to go. It is pricey so I can't do it often, but for a special event it can be worth it. The ingredients are all natural but the result is great. I got three recently, for my wedding shower, bachelorette night and wedding. I even got compliments on how good it looked.
I've had more conventional machine spray on tans many times in the past and this was a very different experience. You have to be comfortable in wearing nothing (or almost nothing) but you get a custom tan according to your color and skin history.
Erika is very personable and makes you comfortable during the process. My only complaint is the price so it's a splurge. Other than that, it's pretty great. My color lasted about a week. It did fade better than the at-home tanners too, less splotchy.
