Quick answer

To fit the Bougainvillea bralette, start with your underbust measurement for the band, then check that the triangle cups cover your breast tissue without digging or gaping. Adjust the straps and band for a snug, comfortable fit that stays in place.

Why band fit matters most in a soft-cup bralette

Unlike underwired bras, the Bougainvillea bralette relies on its band and straps for support. A band that is too loose will let the cups shift, while one that is too tight can dig into your ribs. The band should feel secure but not restrictive, and you should be able to fit two fingers under it comfortably.

How the triangle cup affects coverage and support

The Bougainvillea bralette features a triangle cup, which offers a natural shape and light support. This style works well for smaller to medium busts, but if you need more lift or coverage, a different bralette style may suit you better. The silk and stretch lace combination provides a soft feel with some give, so the fit should be snug without compressing.

Step-by-step fit process

Measure your underbust: Wrap a soft tape measure snugly around your ribcage, directly under your bust. Round to the nearest whole inch. This measurement determines your band size. Common mistake: measuring too loosely. The tape should feel snug but not tight enough to leave marks.
Check the band fit first: Put on the bralette and fasten it on the loosest hook (if adjustable). The band should sit level around your body and feel secure without riding up. You should be able to slide two fingers under the band comfortably. Checkpoint: If the band rides up when you lift your arms, it's too loose. If it digs in, size up.
Assess cup coverage: Look in a mirror to ensure the triangle cups fully cover your breast tissue without spilling over the top or sides. The lace should lie flat against your skin, not gaping or cutting in. Common mistake: accepting cup spillover. If tissue spills, the cup size is too small; try a larger size.
Adjust the straps: Tighten or loosen the straps so they sit flat on your shoulders without digging in. They should provide gentle lift but not bear the full weight of your bust. Checkpoint: Straps should not leave deep indentations; if they do, loosen them and rely more on the band.
Move around to test stability: Raise your arms, twist your torso, and bend forward. The bralette should stay in place without shifting or needing constant readjustment. If it shifts significantly, the band may be too loose or the size too large.
