A seamless bra is the only bra that can go well under almost all your dresses.
They have moulded cups with no seams. They show no lines anywhere. They make hide your nipples completely and show no bumps.
Seamless bras offer a smooth and regular look over the dresses, with no visible bumps or roughness, even when worn under a sheer dress, a tight t-shirt or some other body hugging dress.
Almost every style of bra is available as a seamless bra, like push-up bras, minimizer bras, strapless bras, padded bras, etc.
Sports-bras are mostly done in seamless styles to offer a smoother feel and to prevent chafing or pinching of breasts against the irregular end of seams.
Soft cup bras have cups with no under-wires. They rely on the bra band, under the bust, for support to the breasts. The cups can be moulded ones.
They lack a firm structure and this makes them more comfortable to wear.
They may provide you the required shape, control and support. They are more common with women with A or B cup size.
You may wear them at your home or to places where bra has no great role play in the silhouette of your dress.
It's most popular with A and B cup sized women.
