I have just bought this for the first time (the very dark version as I already have a good colour but want to give my legs a going over to even out colour for a wedding) It came with a mitt. it said to spray the lotion onto the soft side of the mitt, now the mitt has a fine spongy side and a kind of fluffy fabric side. Which side am I supposed to spray on? I cant work out which is "soft"!! I did try it yesterday on the fluffy side it went on ok. today I went for a swim and it faded. Is this supposed to happen? I thought once it was on it stayed for at least a few days. hoping a fake bake expert can help! Thanks
