To achieve the dramatic and lifted "Bridgerton" cleavage reminiscent of the Regency era, you'll want a bra that provides ample lift, push-up, and support to create a rounded, high neckline look. Here are some bra styles and features to look for:

Bra Styles for "Bridgerton" Cleavage:

1. Push-Up Bra: Push-up bras are designed to lift the breasts and bring them closer together, creating enhanced cleavage. Look for bras with padded cups and a plunging neckline.
2. Plunge Bra: Plunge bras have a deep V-shaped front that is ideal for low-cut dresses and tops. They push the breasts together and upward, enhancing cleavage.
3. Balconette Bra: Also known as a balcony bra, this style has wide-set straps and a horizontal cup line, lifting the breasts and providing a rounded appearance. It’s perfect for creating a lifted, Regency-style bust.
4. Corset or Bustier: For a more authentic "Bridgerton" look, consider a corset or bustier. These garments provide support, lift, and shape while also enhancing the waist, contributing to the overall silhouette.

Features to Look For:

1. Underwire: Underwire bras provide excellent support and lift, crucial for achieving that high, rounded look.
2. Padded or Moulded Cups: Padding or moulded cups help shape the breasts and enhance cleavage. Look for bras with graduated padding that is thicker at the bottom of the cup.
3. Wide-Set Straps: Bras with wide-set straps help to push the breasts inward and upward, creating more pronounced cleavage.
4. Adjustable Straps and Bands: Ensuring a perfect fit is key to achieving the desired look. Adjustable straps and bands help you customize the fit for optimal support and lift.

Additional Tips:

• Posture: Good posture can also enhance the appearance of your bust. Stand tall with shoulders back to naturally lift the breasts.

By selecting the right bra and ensuring a proper fit, you can achieve the lifted and pronounced cleavage reminiscent of the elegant styles seen in "Bridgerton."
