How to Choose Your Dress for a Formal Event

Choosing a formal dress that fits your vibe and the event is half the fun of going out. Here are a few tips on how to select a beautiful long formal dress that will have you feeling confident and comfortable at your special celebration.

Consider the Season and Venue. In the spring, at outdoor settings, and during daytime events, formal prom dresses in pastels and other bright hues look best. For evening events, celebrations in the winter, and parties at fancy formal venues, bold colors or rich jewel tones are go-to shades for formal dance dresses.

Get Inspired. Part of choosing a formal dress is looking for style inspiration. Instagram, Pinterest, and YouTube are great places to start gathering ideas. You can also check out new formal dress trends on the runway, see what styles are being worn on the pageant stage, and check out what your favorite celebrities are wearing to their formal events this season. See flattering styles that match your personality? Then shop for formal evening dresses in similar designs to find one that’s just right for you.

Decide on Fabric and Color. When picking the color of your formal evening gown, you can always just go for your favorites, or you can aim to highlight your skin tone with complementary hues. For fabric, consider the different look and texture of each material and how it makes you feel. Do you love the way silk feels against your skin or the way chiffon flows with movement? Then choose a silk or chiffon formal dress for your next event. Do you like the way jersey fabric hugs your curves? Then choose a simple formal dress in jersey and celebrate your figure. If you like sparkle, go for a glitter-knit dress or a formal gown with sequins and rhinestones. Whatever your fabric or color preference, there are lots of fancy styles from which to choose.

Keep it Classic. When in doubt, a classic black formal dress is always in style. Other timeless styles include elegant long formal gowns with lace, sleeved long formal dresses, and strapless simple prom dresses.


Follow these tips and feel confident that your chosen formal dress will be just right for you and your special occasion. Shop PromGirl’s collection for a formal evening gown that takes your night from special to extraordinary.
