Spray tans look really gorgeous and I would recommend getting one now to test the colour and make sure you are happy with the shade. The tans are specifically made in shades designed for different skins and it is best to test them first especially before such a big day as your wedding! One shade might be completely orange on you whereas the next is golden and perfect. If you decide to get a spray tan for your big day, get it a couple of days before the wedding day in case it is streaky or splotchy and then you will have a chance to fix it up if you need to without leaving it too late. Don't forget to exfoliate and shave/wax beforehand and go with clean skin (no moisuriser except on hands and no perfume or deoderant) and take dark loose clothing to wear home afterwards. And an umbrella if its raining lol. Your therapist will be able to tell you how to look after your tan too when you get it done, good luck
