Would it be ok to wear a balcony bra with a strapless dress?

the dress comes down without one and my poke out like melons because they won't stay in! my strapless bras aren't short enough so I need to wear it over a balcony bra, the dress is a pink top shop one with cream polka dots and the bra is the same colour. It kind of looks like part of the dress, do you think this would look ok?
