Nails
On your special day, you want everything to look beautiful. Don't forget your hands and nails. You can choose to have your natural nails manicured and painted or you can go with nail enhancements such as tips or gels. If you decide to use enhancements, I recommend that you get them done a month or so in advance to get used to them and then go in for a fill and touch-ups on the morning of your quinceanera. If you can't work in an appointment the day of the quinceanera, go as late as possible the night before and wear cotton gloves on your hands to protect the polish.
Nail color should enhance your gown and not compete with it. I think a nice French manicure with pretty white tips always looks elegant. You may also opt for a simple nude or pale pink color. If you have a theme that allows, you can be a little bolder with your nail polish. Red nails would be spectacular in a black and white themed quinceanera.
And don't forget the nail art. Although you can now get many intricate kinds of nail art, don't go overboard with it. If you have a very simple gown, you can have more on your nails, but a poofy or busy gown won't work with very involved nail art. For a compromise, ask the nail artist to put the art on only one finger per hand. You can also add small adhesive rhinestones to your nail polish. These are very pretty and add just the right touch of sparkle. You can see lots of nice examples of nail art on the nails section of my resource pages.
No matter what type of nails you choose for your quinceanera, you will need to keep your hands soft and smooth. Get into the habit of applying a chemical-free lotion to your hands after you wash them. A small amount of hand cream or lotion will keep them glowing right through your big event.
