A push-up bra is a type of women's undergarment designed to enhance the appearance of the bust. It features padded cups that lift and support the breasts, creating a fuller look. The padding can vary in thickness, allowing for different levels of enhancement depending on personal preference. These bras are often worn under various types of clothing, including dresses and tops, to provide a more pronounced silhouette. Many styles also include adjustable straps and underwire for added support and comfort. Push-up bras are popular for special occasions or everyday wear, depending on the desired effect.
