If you are the bride, you are going to want to look extra special on your wedding day. Some things you should do before you get married is to have a trial run of everything. If you are getting your nails done, have them done about a month before so you can see if you like the manicurist work. And if you are adding fake nails you will need some time to get used to them.
Have a run through with your hairdresser as well and your makeup person. Make sure you like the two together before the big day. Also try on your dress to not only make sure it fits but to make sure your jewelry goes well with the dress and the shoes.
If you do all of these things then your wedding day will be great. You will look and feel confident knowing that you look your best because you did the essential prep work for it.
