Fancy push-up bras aren't the only way to get the job done. Below are a few tricks that can add a little "oomph" to your bust line:

A convertible bra with the straps configured in an "X" on the back creates instant lift and pushes the breasts together for a very flattering look.

If you feel like the cotton inserts in more traditional padded bras are too clumpy or unnatural looking, try a silicone bra insert, which will give you the eye-catching look of silicone implants without surgery. Browse Amazon.com for silicone bra inserts (they look a lot like chicken cutlets) available in a variety of sizes and price points (anywhere from $12 to $48 and more). These are also great for women who have breasts that are different sizes and wish to even out their chest.

When you're in a pinch, why not try wearing two bras at once? Start with a pushup bra for lift and supplement with a traditional two-strapped bra to provide extra support and a slight bump in size. This works great under T-shirts and sweaters.

Tip #4 - Use Your Clothing and Accessories to Play Up Your Chest

Once you've got your undergarments in place, it's time to put together a look that will play up what you've got and create an illusion of volume up top. Start with a top or dress that has detailing - ruffles, beading, bows - at the bust line. Horizontal stripes also work to accentuate the size of your chest, particularly when using large bands of color. Empire waistlines, wide lapels, pockets on the breast and gathered or ruched bust lines also work to fool the eye.
