Strapless Bras

Freedom, support and elegance for your necklines

The strapless bra is the great ally when you want to wear dresses, off-the-shoulder tops or garments with a sweetheart neckline. Its main function is to offer firm support and an invisible fit that lets you move with total freedom without worrying about visible straps or uncomfortable slipping.

At Promise we design comfortable strapless bras made with non-slip silicone bands, reinforced contours and high-quality breathable fabrics. Whether you’re after a lightweight strapless bra or need maximum support for special garments, in our collection you’ll find the best strapless bra suited to your style.

A variety of strapless bra styles

Each type of dress or neckline calls for a different pattern. In our online shop you’ll find a wide range of options designed to offer a flawless fit:

• Push-up and ultra push-up strapless bras: Ideal for lifting and centring the bust subtly, creating a rounder neckline under fitted garments. If you’re after extra lift, we offer push-up strapless bra options and balconette styles.
• Foam-cup bras with removable straps: Multifunctional solutions that let you wear the straps in the traditional position, crossed, or remove both for complete versatility
• Corselettes and bridal bras: Sophisticated designs with beautiful lace that provide all-over support across the torso, ideal for wedding dresses or special events.
• Strapless and backless bras: Strapless backless bra styles or low-back designs, ideal for party dresses or garments with pronounced cut-outs.
• White strapless bras and neutral tones: Essential basics in white, black or ivory, ideal for wearing under light or sheer clothing.

Strapless bras that give great support in every size

There’s a myth that wearing a strapless bra is only for small busts, but advances in pattern design now make flawless support possible whatever your size.

Frequently asked questions about strapless bras

How can I stop a strapless bra from slipping or falling down when I walk or dance?

For a comfortable strapless bra to stay in place, the band around the ribcage must fit perfectly, since it supports 80% of the bust’s weight. Make sure to choose a style with non-slip silicone strips on the inner edges, and avoid applying body cream or oil to the chest and back area before getting dressed, as moisture reduces the grip of the silicone on the skin.

Does a strapless bra for a large, fuller bust really work without flattening the bust?

Yes, it’s entirely possible. The best strapless bra for a large bust replaces the function of straps with clever pattern engineering: extra-wide bands with flexible side boning, reinforced under-bust boning and high-coverage cups. This allows a strapless bra for a large, fuller bust to keep the bust lifted, centred and supported from the base, without compressing or flattening it.

What kind of strapless bra should I choose for a sweetheart-neckline or low-back dress?

For a classic sweetheart neckline dress, a push-up strapless bra or balconette style is ideal, as it lifts the neckline and rounds out the top of the bust. If the garment has a plunging neckline at the back, the best solution is a strapless backless bra or a multiposition-strap low-back style, which repositions the closure band further down the waist without losing firmness.

Should I buy a smaller band size so it grips tighter and doesn’t move?

It’s not advisable. Buying a size smaller than your own will cause uncomfortable marks on the skin, reduce breathability and push the bust upward or outward (creating the “double bust” effect). The key with a plus-size or standard strapless bra is to measure your underbust accurately and choose your usual size; the garment’s non-slip bands will take care of the grip without needing to squeeze the ribcage.

Is it uncomfortable to wear a strapless, wire-free bra all day?

Quite the opposite. Wire-free strapless bra styles are designed with everyday comfort in mind, using high-density microfibre fabrics and gently compressive elastic bands at the base. They are comfortable, invisible strapless bras, perfect for summer outfits or long events where you want total freedom of movement without rigid structures.
