Description

Fiona is a full band underwire bra pattern with 4-part bra cups and a matching panty.

View A: Full band underwire bra with a top cup, two lower cups that are separated by a vertical seam, and a power bar. This type of bra construction helps to –

  • Provide side support: Especially useful for people with fuller busts or wide-set breasts as it keeps the breast tissue from spilling out toward the underarm.
  • Improve projection: By pushing the breast tissue inward, it enhances forward projection, giving more lift.
  • Offer Shaping: Helps create a more rounded silhouette.
  • Increase Stability: Distributes the weight more evenly.

The bra is an ideal style for people with a pronounced stomach, fuller ribs, or a body shape that widens from the ribcage to the waist. Designed without a bottom band, it sits comfortably at the breast root, eliminating the common issue of band roll-up for many wearers. The bra also has adjustable shoulder straps and a hook and eye closure at the center back.

View B: A high-waisted panty with matching lace panels on the front and a soft mesh back for comfort. The waist and leg openings are finished with wide fold over elastic.
