The difference between an underwire, shelf bra and moulded cups

Ever wonder what the difference is between all the different bust support available? We’ve made it easy for you and explained all the different options available below:


Underwire Bra- An underwire bra has a thin rigid piece of metal, plastic or resin sewn into the underside of the cup of the bra. The purpose of the underwire is to provide additional support for the breasts. Underwire provides shaping and support, pushing the volume of the breast in an upwards and out direction. If you are looking an underwire in your bathers, head to our underwire swimwear section.


Shelf Bra- A shelf bra is a type of bra that supports the lower part of the breasts, equipped with an elastic band at the base to lift breasts up. Shelf bras are also known as ‘built-in bras’ and can be commonly found in camisoles, tank tops, and swimwear of course. 


Moulded Cup- Moulded cups are generally seamless, giving you a natural, rounded shape and sometimes have padding to prevent your nipple from coming through the material. Moulded cup bras are commonly found in sport bra styles, nursing bras and Tshirt bras including many of our swimsuit choices.
