If you don't want to wear a bra beneath your clothes, you don't have to. But many women wear bras to support their breasts and improve the look of their clothes. Bras can ruin clothes if they peek through or if other people see the shoulder straps. If you do want to dress without a bra, there are some things to keep in mind. Does this Spark an idea?
Consider wearing a top with support. Many tops and dresses, especially tank-top-like blouses or halter tops come with built in shelf bras. Shelf bras give you some support without you having to wear a bra. But if you're large chested, you may find a top with a shelf bra doesn't give you enough support.
Have support built into your clothes. For special dresses, such as wedding dresses, many women have tailors add underwire or boning to the dress, so they can go without a bra.
Check your clothes. If you are going out without a bra, get dressed, then jump in place, walk back and forth in front of the mirror and bend over. Make sure you can't see your breasts through your shirt. If you don't like what you see, don't go braless.
Take off your top and put on a bra. Then see what your outfit looks like. You may find your outfit looks better if you wear a bra underneath it.
