What’s the difference between a full-cup bra and a half-cup bra?

The bra is a piece of lingerie with a long history, which has seen the emergence of several different bra styles over time. 

The full-cup bra and the half-cup bra are two timeless lingerie staples found in almost every lace drawer… or nearly. The full-cup is the most covering and supportive model, yet it remains elegant. The half-cup bra is a bit sexier, revealing more of the bust for a more open neckline. Shape, support, effect on the bust — here’s everything you need to know to choose your ideal bra.

 

What is a full-cup bra?


A full-cup bra is designed to fully enclose the bust. Its cups are high, covering, and often reinforced at the sides to ensure excellent support.  It is one of the perfect bras for larger busts, which need firm support every day, without sacrificing comfort. Whether with or without underwires, its mission remains the same: hold, support, and reassure.

What is a half-cup bra?

The half-cup bra focuses more on shaping than coverage. It reveals the top of the bust with a horizontal cut, often slightly crescent-shaped, for a lifted and rounded effect that’s usually very flattering. It also suits fuller busts well, provided it’s well-constructed.

Key differences between full-cup and half-cup bras

  • Cup shape: The full-cup bra envelops the entire bust, from the base to the top of the breast. The half-cup bra reveals the upper chest — its cups stop at the top third, creating a subtle cleavage-enhancing effect.

 

  • Support level: The full-cup offers the strongest support. It’s often considered the go-to bra for larger busts. The half-cup provides lighter support for larger sizes seeking a more open style.

 

  • Final look: The full-cup gives a natural, round, and uniform shape. The half-cup creates a more lifted, rounded, and flattering effect under a V-neck or open neckline.

 

  • Comfort and use: The full-cup bra is often chosen for everyday wear, work, or any situation where comfort and support are key. The half-cup, more seductive and lightweight, is perfect for dressed-up looks, special occasions, or simply the pleasure of wearing beautiful lingerie.

 

Which model to choose based on your body shape?

There is a bra shape to suit every body type. The choice of model therefore depends on your bust size, but also on your outfit and your mood on the day!

  • Small bust? The half-cup bra is a great ally to highlight your natural shape without flattening it. It defines and enhances without adding unnecessary volume.

 

  • Full bust? The full-cup will be your best friend. It provides impeccable support while smoothing your silhouette under clothing.

 

  • Sagging bust (naturally or post-pregnancy)? Opt for the full-cup. Its high and enveloping shape helps reposition the bust and offers a beautiful contour without compression.

 

  • Fuller at the bottom than the top? (volume concentrated at the base of the breast, with little tissue at the top): go for a full-cup or a model with centered straps and well-structured cups. This helps lift the bust and visually balance the shape.

 

  • Looking for a discreet model? Choose a full-cup in microfiber — simple and effective. 

 

  • Love sexy details? A half-cup in delicate lace or embroidery will be the perfect glamorous touch, especially if you’re looking for a cleavage effect with a bit of volume.

 

Don’t confuse these two styles anymore

The full-cup bra is your best ally if you’re looking for optimal support, an enveloping cut, and everyday comfort — especially for fuller or sagging busts.
The balconette bra focuses on femininity with an open neckline and a beautifully rounded shape — ideal for medium to small busts or to enhance a more dressed-up look.
Each shape has its purpose: choose based on your body type and style preferences. And for a perfect lingerie drawer, both can coexist beautifully.
