Shelf bras & open cups

Contrary to its appearance, open bra really supports bust. Especially if choosing model suited to your body shape.

Open bra structure relies on underwires positioned under and around bust, exactly like classic bra. These underwires do support work, not cup fabric. Quality models also integrate side stabilisers (elastic bands on sides) keeping bust centred and preventing spillage.

For fuller busts (E+ cup), seek models with reinforced underwires (fabric-sheathed steel), wide straps (minimum 1.5cm) and wide back (4 hooks minimum). These elements comfortably distribute weight. Good test: raise arms above head.

If bra rides up or you feel bust moving excessively, support is insufficient. Perfect fit feels firm but never uncomfortable, and bust must stay in place during normal movements.

Size works exactly like classic bra: back size (32, 34, 36...) + cup (A, B, C...). If usually wearing 34C, order 34C in open bra. Caution however: some models with elastic harnesses or particular structures may size slightly differently (S, M, L, S/M...).

Key checks for fit:

• Back size: Must be firm and horizontal (doesn't ride up back). You must be able to slide two fingers under elastic band, no more. If too tight, go up back size and down cup (ex: 32C → 34B, same volume).
• Underwires: Must completely surround bust without pressing on breast tissue. If pressing on breast rather than underneath, cup is too small.
• Straps: Should support about 10% weight only. If marking shoulders or you must tighten to maximum, back size is too large.
• Centre (part between two cups): Must rest flat against sternum. If floating, cup is too large. If pressing on breast tissue, cup is too small.

Yes, but strategically. Open bra generally isn't designed to be invisible under clothes (that's not its role), but can create sophisticated effects when partially visible:

• Under half-open shirt: Leave 2-3 buttons open revealing lace details or elastic harnesses. Sexy-chic effect for romantic dinners or evenings.
• Under open blazer: Structured blazer worn with nothing underneath (or with bralette/open bra) and high-waisted trousers creates modern, daring look.
• Under sheer or lace top: Open bra becomes integral part of look. Layer with jacket or gilet to modulate according to context.

To avoid: Wearing open bra under figure-hugging t-shirt or fitted dress. Underwires, harnesses and cutouts will mark and create unflattering visible lines. For these outfits, opt rather for classic invisible bra or smoothing bodysuit.

Open bras, especially those with delicate lace or metal details, require careful care to preserve structure and beauty:

• Hand washing compulsory: Fill basin with warm water (max 30°C) with specialist lingerie detergent or mild soap. Immerse bra and press gently (never rub). Rinse abundantly with clear water.
• If machine absolutely necessary: Use closed washing bag (or knotted pillowcase), delicate 30°C programme, minimal spin. But really, prefer hand.
• Drying: Never tumble dryer (would destroy elasticity and underwires). Lay flat on clean towel, reshape cups by hand. Avoid hanging by straps (stretches elastic).
• Models with chains, metal rings: Check before washing no metal is rusty. If yes, don't wash (or remove metal elements if possible). Metal can bleed and stain lace.
• Storage: Store flat or hung by centre gore (never by straps). Don't fold cups into each other (warps underwires).

Lifespan: Quality open bra, well-maintained, lasts 6-12 months with regular wear (2-3 times/week). Signs to replace: stretched elastics, underwires coming through fabric, torn lace, or lost support even at tightest hook.

Colour choice depends on your style, complexion and intended use:

• Black: Timeless classic. Sophisticated, slimming, easy to match. Perfect for first purchase as versatile. Works on all complexions. Black is also most "safe" to begin in daring lingerie: reassures whilst remaining sexy.
• Red: Colour of passion and embraced confidence. Spectacular and memorable. Ideal for special occasions (Valentine's, anniversary). Favour deep red (burgundy, wine red) rather than bright red if beginning.
• White or ivory: Romantic and delicate. Perfect for weddings, honeymoons or softer aesthetic. Caution: white can show through under pale clothes and requires impeccable care (visible stains).
• Nude/beige: Less common in open bra but very chic. Blends with complexion for sophisticated "second skin" effect. Choose shade close to your skin tone.
• Bright colours (fuchsia, emerald, electric blue): For most daring. These shades assert personality and break from classic codes. Reserve for second or third purchase when comfortable with concept.

Practical advice: Start with black or red (two safe bets), then expand collection according to desires and experience feedback.

Yes, if well-chosen, but comfort depends on model quality and fit. Quality open bra with correctly positioned underwires and adapted materials can be worn several hours without discomfort. Here's what makes difference:

• Quality underwires: Flexible fabric-sheathed steel (not hard plastic) embracing natural curves without pressure points. Cheap underwires break quickly and create discomfort.
• Adjustable, wide straps: Allow distributing weight. Too-thin straps cut shoulders after 1-2h.
• Breathable fabrics: Quality lace, cotton-lined or microfibre. Avoid low-grade synthetics making you sweat.
• Flat seams: Don't rub skin. Thick or poorly finished seams irritate after few hours.

Reality: Open bra remains above all seduction lingerie designed for special moments rather than all-day daily wear. Its role is primarily aesthetic. For daily, classic bra or bralette will always be more practical. But for evening, dinner or few hours? Absolutely comfortable if well-fitted.

No difference: they're two terms designating same product. "Shelf bra" or "uplift bra" are alternative names for open bra, meaning demi-cup or open-cup model supporting and glorifying bust whilst leaving part visible.

Term "shelf bra" emphasises support and glorification function thanks to underwires positioned under and around bust. It's particularly relevant for models creating spectacular push-up or pigeon-breast effect. Whatever name used, structure remains identical: support underwires, demi-cups or cut-out cups, adjustable straps and elastic back.

Note: Term "open bra" is more common in contemporary lingerie and better conveys concept (cup opening), whilst "shelf bra" is more technical name sometimes used for models with strong control effect.
