Article: What to Wear Under a Race-Day Dress

What to Wear Under a Race-Day Dress

The dress is decided. What sits underneath it decides how the day feels.

Race day is long. There is the train, the walk across the lawn, hours of standing, the heat of early November. A piece that feels fine for ten minutes in the mirror needs to feel just as good at five in the afternoon.

The right piece underneath is what lets the outfit work. Here is how to choose it, starting from the dress.

For a strapless or off-the-shoulder neckline

Start with a strapless bra built to hold on its own.

The Bye Bra Strapless Bra has moulded, wired cups and a silicone strip along the upper wing, with extra boning through the side so it does not twist or slip. Eight hook placements let it convert to a standard, cross-back or one-shouldered style, so it works for more than one dress.

For a lower neckline, the Bye Bra Deep Plunge Strapless Bra has wire-free moulded cups cut low at the front.

If you prefer the structure of a true underwire, the Else Bare Underwire Strapless Bra has a wide backband and five-by-three hook-and-eye closure to carry support through a full day, all in Else's signature sheer fabric.

For an open back with a fuller bust

When the back is bare and you still want defined support, the Bye Bra Sculpting Breast Lifts are the answer.

Adhesive cups with an embedded underwire give structure and shape. A long, transparent shoulder strap adds targeted lift and keeps each cup in place. Available from C through to H.

For an open back, halter or plunge with a smaller bust

The Bye Bra Invisible Bra is applied one cup at a time, then clipped together at the front for lift. There is nothing at the back or shoulders, so it suits backless, strapless and halter styles alike. With care, it can be worn up to 50 times.

For sensitive skin

If adhesive is not for you, the Bye Bra Silicone Rabbit Bra Cups give lift and coverage without it. They are dermatologically approved, hypoallergenic and reusable up to 50 times.

For a low back that needs structure

Some dresses call for one considered piece rather than several.

The Bye Bra Low Back Bodysuit Thong has a wire-free moulded cup for shape and a concealed backband for reinforcement. Long, adjustable straps fit into three different back placements, and a spare set of clear straps is included. A press-stud gusset makes the bathroom queue simpler.

For a fitted or bias-cut skirt

Under a fitted dress, the Bye Bra Invisible Short gives a smooth line with no visible panty lines. Laminated finishings keep seams to a minimum for a second-skin feel, with medium control through the lower tummy. It is a comfortable layer to stand and walk in all day.

Before the day

A few things worth doing in advance.

  • Try everything on with the dress, not on its own. Sit, walk and raise your arms.
  • Apply adhesive pieces to clean, dry skin, without body lotion or oil.
  • Pack a spare. Breast tape or a second set of cups takes up almost no room in a clutch.
