How to Dress Up Any Plain Outfit. A plain outfit doesn't necessarily mean that it must be a boring outfit. The right accessories and the right shoes will effectively dress up any plain outfit. Here's how to use a little imagination to dress up even the most plain of outfits.
Wear either a wide or skinny belt with a plain black dress to add a little pizazz to your outfit. Think wide leather belts in colors that pop, like red or turquoise, or a skinny belt with a simple metal buckle in any color.
Get the right heels to dress up any plain outfit simply by putting them on. Pair a plain jeans and T-shirt outfit with a pair of sassy red Mary-Jane heels or a pair simple brown paints with some hot pink pumps.
Pick boots. Dark jeans look fantastic tucked into a pair of tall boots. Just make sure the fit on the jeans is a little tighter around the legs before you tuck them, loose jeans tucked into boots will make you look like you are wearing bloomers.
Choose jewelry. Put on fun jewelry such as a colorful chunky necklace to dress up a plain outfit. Select a long gold or silver necklace to dress up a plain black dress. Consider a few gold or silver bangle bracelets or a few fun rings as well.
