The first thing to do would be to buy an enhancing bathing suit. You can get all types of bathing suit, bikini and tankini tops with gel inserts, which are very secure and won't fall out. These suits also have very good support, which enhances what you have got as well as adding the fullness of the gel inserts.
In addition to this, you can apply make-up to the area to maximize the appearance of depth to your breasts. Apply make-up sparingly so it is not obvious and creates a natural looking illusion rather than a covering. It is quite easy to achieve this look, and although you can buy specific make up for enhancing your cleavage this is completely unnecessary. All you need to create this look is two different shades of powder; one dark and one light (the exact shades will be different depending on your skin tone).
Put your swimsuit on before you start so that you can tell which parts of your breasts will naturally catch the light given the support of that particular item. Apply the darker shade down the middle of your chest between the breasts to give the appearance of a more strong shadow. Make sure you blend this outwards towards the top to create a natural looking V shape contour around the breasts. Next use the lighter powder (maybe a face powder or pale eye shadow) to catch the light on the top half of your breasts. Make sure all the makeup is blended well and doesn't look too obvious; it should just be a natural extension of where the light would normally catch and where shadows would form. This effect can be made more waterproof by using fake tan instead of the darker powder.
