At the moment its all about glowing skin. Try to have at least three facials
(one a month) before the big day. This will not only make your skin glow, it will help with the skin texture so you can achieve that flawless makeup look with little effort.
Book a trial run makeup well in advance, this way you can see if you work well with the makeup artist, you can always have another trial run closer to the big day when you are more comfortable with the look you want to achieve.
