How to Choose Your Insert
| Insert | Your Cup Size | Lift Added | Best For |
|---|---|---|---|
| A | A – B | +1 cup | Subtle, natural enhancement |
| B | B – C | +1 cup | Everyday lift & shape |
| C | C – D | +1–2 cups | Noticeable, rounded cleavage |
| D | D – DD | +1–2 cups | Fuller lift for larger cups |
| E | DD & up | +2 cups | Maximum cleavage & support |
Soft, cushioned inserts that lift, shape, and disappear under everything — slip them in and forget they're there.
Grips on both sides to lock in place all day, holds through sweat and water, and reuses up to 40 wears. No glue, no stitching, no irritation — just soft cushioned lift.
From a natural everyday boost to fuller, bolder cleavage — pick the insert size that matches the look you want. Match your cup for natural lift, or size up for more drama.
Slip them into your bra, bodysuit, or plunge top and adjust to the lift you love. Works under deep necklines and backless styles — invisible from every angle.
Rinse gently with mild soap and water after each wear, air dry fully, then store flat in the box. Reusable up to 40 wears — avoid lotions or oils on skin before applying for the longest hold.

Built to last up to 40 wears. Just rinse, air dry, and reuse — no glue, no stitching, no single-use waste.

Use our size chart on each product page. Measure your waist, hips, and bust, then match to the chart. If you're between sizes, we recommend sizing up for comfort or sizing down for more compression.
Our seamless designs have no visible panty lines, no stitching marks, and no bunching. They sit completely flat under dresses, work pants, jeans, and fitted tops.
Our shapewear is designed for all-day wear — 8 to 12 hours comfortably. The breathable fabric prevents overheating and the compression is firm but not restrictive.

US orders ship within 1–2 business days and arrive in 3–7 business days. Express shipping is available at checkout. International orders take 7–14 business days.

Hand wash in cold water with mild detergent and hang dry. Do not bleach, iron, or tumble dry. This keeps the compression and fabric lasting longer.
