Coral or tan, chiffon or silk, long or short? The possibilities are endless when it comes to finding the perfect prom dress. Before you make a choice, sit down and think about your options. Make a game plan to streamline the process so it’s fun, instead of stressful. Remember, though going to prom will be one of the most memorable experiences you will have during high school, finding the dress should be just as exciting.
Part 1 Researching Before You Go
1. Check the runway.
If you are the trendy type and want to be current on the latest must-have designs, watch the red carpet. See what your favorite celebrity is wearing and either steal their style or incorporate it into your own.
Unlike a wedding dress, prom dresses come in many different colors and styles! One thing to consider when buying a prom dress is picking a color that best suits you. Choosing the right prom gown in a color that's flattering to your skin tone and eye color will help you stand out on prom night.
Method 1 Determining your Skin Tone
1. Analyse your skin's surface tone and undertone.
Your skin tone is the surface color of your skin and is usually the word you use to describe your skin color (ex. Ivory, light, medium, dark). Your skin’s undertone is the color underneath the surface. It is possible to have the same surface skin tone as someone, but different colored undertones. When shopping for a dress you should take both the surface tone and undertone into consideration. 
Undertones are typically broken down into three categories: cool (pink, red, or bluish), warm (yellow, peachy, golden), or neutral (a mix of warm and cool).
It can be super frustrating to walk into a shop and have to wade through dress after dress to determine your size! Not to worry. Although dress sizes are different at most stores, as long as you know your measurements, you shouldn't have a problem figuring out which sizes work best for you.
Part1 Measuring Your Dress Size
1. Measure your bust.
You'll need to measure the fullest part of your bust to get the proper measurement. Make sure that the measuring tape (a dress maker's soft tape measure for preference) goes under your arms.
There are very few times in your life when you get to wear a truly glamorous, jaw-dropping dress. Why not make your prom night one of those times with a beautiful, flattering, perfect prom dress?
1 Plan to choose and purchase your prom dress around four to six weeks before your prom.
Many formal gowns (including prom dresses) require alterations for a perfect fit, and you will want to allow enough time to complete these alterations.
