"Balcony bra" may sound like a strange name. Well, this is probably the case because the phrase is actually a shortened version of the true name - a "balconette bra". Regardless of what you call it, the bra truly does act somewhat like a balcony. It provides significantly more support around the bottom of the breasts, creating a "balcony" of sorts.
This balcony effect also reveals the purpose of the bra. The upward pushing effect creates...well, an upward push. This makes the breasts appear more buxom. You can wear it for this sole effect, but most women amplify the effect by wearing a top that shows a lot of cleavage. The balcony bra is excellent at creating that deep cleavage look that men seem to find so enticing.
At this point, you might be thinking the balcony bra sounds a lot like a half cup bra. You're right. The primary difference is the cut of the bra. The cups are cut in such a way that the material doesn't slide up into the cleavage area. The top of the cup is also cut lower than a half cup bra. This allows you to wear tops that have not only deep cleavage, but show a lot of the width of the chest. Worried about the straps showing? They are attached in a broad set that places them closer to the shoulders than with normal bras.
Many specialty bras are a pain to own for two reasons. One, you can only wear them on certain occasions because they fail to provide the necessary support or comfort for other occasions. For example, most women do not walk around in strapless bras! The second reason ties into the first. Bras are not exactly cheap and that is important these days. Owning bras you can only wear every so often just doesn't make financial sense. Fortunately, the balcony bra does not have these problems. Since it offers massive support from the bottom up, you can wear it with practically any outfit.
If you don't own a balcony bra, you should give them a closer look. A quality balcony bra is versatile and can really create a look that will leave them with the tongues wagging.
