You have a big event scheduled, and you haven't a thing to wear. Don't despair! The selection of formal dresses in plus sizes has never been greater with the growing number of specialty retailers that cater to full-figured women. Whether you are in need of a bridesmaid gown, a prom dress, or a full wedding ensemble, you can find a bevy of choices. Before you head to your local mall, though you'll need a few guidelines for shopping for formal dresses in plus sizes.

Many special event dresses are by special order only. This means that you'll be measured for your dress, and the shop will place an order with the manufacturer. Generally, the retailer will ask for a deposit of up to 50 percent with the remainder due at the time you receive the dress.

While some special order, formal dresses in plus sizes can be ordered and received in less than a month, you can expect a wedding or bridesmaid gown to take up to six months for delivery. So, it is essential to plan ahead.

If you are short on time, there are many options for purchasing formal dresses off the rack. Boutiques that cater to plus size women and large department stores will have a bounty of different styles. You may also want to try searching online retailers, and there are many of them that specialize in plus size formal wear. If you are looking for a one of a kind gown, consider perusing the racks of vintage clothing shops or consulting with a dressmaker who can design a gown just for you.

As you sift through the different dress options, keep in mind the three "C's" of dress selection - cut, color, and comfort. First, look for a style that is flattering to your body type. Larger figures often look good in halter style dresses.

Then, consider the appropriate color. Perhaps, you need to stick with a color scheme of the wedding or party. If you have carte blanche to pick the color you want, you may want to select a dark shade that will slenderize.

Finally, comfort is of the utmost importance, as you will probably be spending several hours in the dress. Try on gowns and dresses with the right undergarments, and see how they fit and feel. If you have to tug on straps or suck in your tummy, you probably need a different size or style.

So, go ahead and look forward to that special occasion. With a little advanced planning you can have the perfect formal look that will give you the confidence to strut your stuff.
