Maidenform's Feeling Sexy Ultimate Gel Push Up Bra ($22-$34) offers soft, gel-filled cups for natural-looking bust enhancement. It's comfortable, affordable, and practical. While it isn't a bra for someone interested in the extreme cleavage effect, it does a great job adding fullness to your form.

What would a discussion about push-up bras be without a nod to Victoria's Secret? They encourage women to unleash their inner vixen with products like the new V-Plunge Push-up ($52), a bra that begs to be worn with your most daring necklines. It features a deep-plunge shape and structured cups that lift and beautifully enhance the bust line. While reviews of this and other products from Victoria's Secret are generally positive, the cost of the products seems to be a concern to buyers. Many feel they could have gotten a similar bra for a lower price. However, Victoria's Secret does offer a huge selection, and the shopping experience can be crazy fun, so you might want to check it out if you can afford the splurge.
