Materials

Material: 100% Polyester and Silicone Glue.

Instructions

Application

Make sure your skin is clean and dry before applying.

Put your outfit on first, then slot your enhancers into position on the inside of your clothing.
Use one hand to scoop your breast up into position and the other to press the enhancer firmly against your chest.
Repeat on the other side.

Removal

Support your breast with one hand and gently peel the enhancer away from your skin with the other, then slowly peel it off your clothing. Any glue left behind will wash away.

Cleaning

Use a gentle soap that contains no moisturisers, oils, fragrances, conditioners or added hydrators. Many soaps and hand washes contain hidden conditioning agents that leave behind a residue, which can weaken the adhesive over time.

Hand wash with warm water, let them air dry, then put the protective film back over the adhesive, ready for next time.

Good to know

Wear for up to 6 to 8 hours.
Don't use on sensitive, broken, irritated or sunburnt skin.
If you feel any discomfort, remove them straight away.

Are they right for me?

Find out if they're your match.

Would they work for me?

Double Boost is made for you if:

You have a smaller bust and want noticeable volume, up to two cup sizes.
Your breasts have lost some elasticity and the volume they once had. Pressed against your skin and held by a structured fabric, Double Boost adds that volume back and keeps your chest secure. You get better shape and fuller projection across your chest.
Your outfit has room at the bust that you don't quite fill. Think wedding dresses, strapless gowns and formal dresses. Double Boost fills that space and holds everything in place all day, which is why they're so popular with brides and for formals.

They're padded thicker than our other enhancers, so they're all about creating fullness and shape.

How do they work with my outfit?

Double Boost works with two types of fabric.

Stretchy fabrics need to be snug. Do the pull test: if you can easily pull the fabric away from your chest, it won't have enough grip to hold the enhancers in place.

Firm fabrics with no stretch, like structured cottons and linens, work well as long as they sit close to your body and press the padding firmly against your chest.

If your outfit sits loose, even in a heavier fabric like silk or satin, the padding has nothing holding it in and it will stick out.

If they slip or stick out, your outfit needs to be either more fitted or more structured.

Tip: if your outfit has straps, adjust them so the fabric is really supporting your breasts.

Who they're not right for

They're not recommended for augmented breasts. Because implants have a firm, round shape, the enhancers may not sit flush against your chest and could show under your clothing.

They also won't work with thin, flimsy fabrics, or with stretchy fabrics that sit loose against your chest.

If you'd like a more natural look, Subtle Boost adds about one cup size, and No Boost gives you lift without adding size.

How to apply

Step 1

Make sure your skin is clean and dry before applying.

Step 2

Once your outfit is on, slot your enhancers into position on your clothing.

Step 3

Use one hand to scoop your breast up into position and the other to press the enhancer against your chest to hold it in place.

Step 4

Press down firmly and repeat on the other side.

Choose the right outfit

Double Boost works with two types of fabric:

Stretchy fabrics, like tight elastane: these need to be super snug. Do the pull test: if you can easily pull the fabric away from your chest, it won't have enough grip to hold the enhancers in place.
Firm fabrics with no stretch, like structured cottons, linens and double lined materials: these need to sit close enough to press the padding firmly against your chest.

Double Boost Q&A

What are Double Boost breast enhancers?

Our Double Boost Breast Enhancer Inserts are premium, thick padded inserts designed to visibly enhance your bust by up to two cup sizes. They are crafted to add instant volume, lift, and shape while remaining smooth and seamless under clothing.

The inserts adhere securely to both your skin and your garment, allowing them to stay comfortably in place throughout the day. They are best worn with tight or structured fabrics, where they work with your outfit to create a fuller, more sculpted silhouette.

Double Boost Inserts are ideal for enhancing cleavage, filling out low cut or form fitting styles, and adding balance and confidence to outfits where you want extra volume without wearing a bra.

Which enhancer should I choose?

It depends on the look you’re going for and the style of outfit you want to wear them with.

No Boost gives you lift and elevation without adding size.
Subtle Boost adds lift and about one cup size.
Double Boost adds up to two cup sizes for maximum volume.

If you want maximum volume, up to two cup sizes, Double Boost is your match.

Then check your outfit:

Look at the cut and fit. How is it shaped around your bust?
Can you adjust the straps to give you more lift and support?
Does the fabric sit close enough against your chest?

Still not sure? Send us a message and we'll help you find the right match for your outfit.

Which size should I choose?

Choose your size based on your outfit, not just your breast size.

If your outfit gives you fuller coverage, go with your usual size.

If your outfit is more revealing and doesn't cover your whole breast, size down. You don't want the enhancers to be the same size as your breasts, or the padding will stick out past your garment. The enhancers only need to slot in behind the fabric, while your own shape does the rest.

For example, if you're usually a large but you're wearing a skimpy top, a small will often sit better and stay hidden.

How should I wear the inserts?

With snug, structured clothing. Because they're padded thicker, they need a snug fabric to hold them firmly in place.

Will they show through my clothing?

Not when they're worn with the right fabric. Because they're thicker and more padded, they need a snug, structured outfit to keep them in place and stop them sticking out at the sides.

Are the breast enhancer inserts reusable?

Yes! All our inserts are washable and reusable. Gently hand wash them with a liquid soap or detergent that has no moisturisers, then let them air dry. With the right care, they'll last 10 to 15 uses.

Will the inserts stay in place throughout the day?

Yes, the inserts are designed to adhere securely to both your skin and clothing. As long as you're wearing them with structured or tight fitting garments, they should stay in place comfortably throughout the day.
