Learn how to fit the Lumiere Underwire Bra for optimal support and comfort. This guide covers sizing, adjustments, and key features like the three-piece underwire profile.
Quick answer
To get the best fit from your Lumiere Underwire Bra, focus on the underwire placement, cup volume, and strap adjustment. The three-piece underwire profile provides support with a natural shape, but only if the wire sits flat against your ribcage.
Why underwire placement matters
The Lumiere Underwire Bra's three-piece underwire profile is designed to provide support with a natural shape and rounded profile. If the underwire does not sit flat against your ribcage, you may experience discomfort or reduced support. A common issue is the wire resting on breast tissue, which indicates the band is too small or the cup is too shallow.
Cup volume and forward projection
The internal cup sling in the Lumiere Underwire Bra provides uplift and forward bust projection. If your breasts spill over the top or you see gaping at the cup edge, the cup volume is likely incorrect. The reinforced bottom cups add support and modesty, so the bra should feel secure without digging in.
How to fit the Lumiere Underwire Bra
- 1. Check the band level: The band should sit parallel to the floor, not riding up at the back. If it rises, the band is too loose. Hook the bra on the loosest set of hooks when new; move to tighter hooks as the elastic stretches. The band provides 80% of the support, so a snug fit is critical.
- 2. Verify underwire position: The underwire should encircle your breast tissue completely, lying flat against your ribcage. It should not rest on breast tissue at the front or dig into your underarm. If it does, try a larger cup size or a different band length. The underwire should sit at the inframammary fold, not on breast tissue.
- 3. Adjust the straps: Straps should be snug enough to stay in place without digging into your shoulders. Tighten them just enough to lift the cups slightly; over-tightening can cause the back band to ride up. The Lumiere straps are fully adjustable, so take time to find the right tension. If straps are digging in, the band may be too loose and taking on too much support.
- 4. Check for spillage or gaping: After swooping and scooping all breast tissue into the cups, look for overflow at the top or sides. Gaping at the top of the cup may mean the cup is too large or the shape is too projected for your bust. The internal cup sling should provide uplift without causing spillage. Spillage means the cup is too small; gaping means the cup is too large or the wrong shape.
- 5. Move and recheck: Wear the bra for a few minutes, reaching your arms overhead and bending side to side. The band should stay level, the underwire should remain in place, and the cups should not shift. If the bra moves out of position, revisit the band and cup fit. A well-fitting underwire bra should feel secure during movement, not restrictive.
