Does anyone know the staying power of either kinds of makeup? I'm looking for something that will last all day - through tears & sweat (the wedding is in May). And something that won't slide off of my shiney T-zone... Also, any suggestions on where to go for wedding day application of either? Or would I be better off going the traditional makeup route (maybe at a makeup counter) with a sealer of some sorts to keep the makeup on??? TIA!!!
