Description
For Best Results
The Subtle Boost Breast Enhancer Inserts are designed to be worn with structured, supportive, or form fitted garments to ensure a smooth and discreet appearance. While the inserts add volume and shape on their own, lift is achieved through the support of your clothing. Structured or thicker fabrics help hold the inserts in place and maintain elevation, whereas overly lightweight or highly stretchy materials may not provide sufficient support for lift.
These inserts can be worn under tops, dresses, and swimwear for a natural, non surgical enhancement.

Instructions
Application
Make sure your skin is clean and dry before applying.

- 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
Hand wash with warm water and a liquid soap or detergent that has no moisturisers. Let them air dry, then put the protective film back over the adhesive, ready for next time.
Good to know

Would they work for me?
Subtle Boost is made for you if:
- Your breasts sit a little lower than they used to and you'd love some of that perk back.
- You have a smaller bust and want to add natural looking fullness.
- Your breasts have lost some elasticity and need both fullness and elevation.
They add about one cup size, so the result looks natural, just a fuller, lifted version of you. They're also handy for filling out structured dresses and tops that gape a little at the bust by securing your fabric to your chest.
How do they work with my outfit?
Snug, structured fabrics with little to no stretch work best, like firm cottons, linens and double lined materials.
That's because the enhancers don't lift your breasts on their own. They work together with your fabric. They stick to both your skin and your outfit, so once you've scooped your breasts into place, your fabric holds them there and keeps them sitting exactly where you placed them.
If your fabric is too flimsy, it can't hold the weight. Your breasts and the enhancers get pulled down, and you lose the lift.
Tip: if your outfit has straps, adjust them so the fabric is really supporting your breasts and holding them up in position. It's an easy step to forget, and it can make a big difference to your placement.
Who they're not right for
If you're after dramatic volume, Double Boost will give you more. If you're happy with your size and just want lift, No Boost is your better match.
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 stick out.
They also won't work with loose, sheer or thin fabrics. Without a snug, structured outfit holding them in place, they can't do anything for your shape.

Get the best hold
Choose the right outfit
Subtle Boost works when your fabric holds your breasts firmly against the enhancers:
- Firm fabrics with little to no stretch, like structured cottons, linens and double lined materials: these hold the enhancers in place best.
- Stretchy fabrics: these 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.
- Adjust your straps so the fabric is really supporting your breasts and holding them up in position.

Subtle Boost Q&A
What are breast enhancer inserts?
Breast enhancer inserts are specially designed pads that add lift and volume to your bust. They come in three styles, No Boost, Subtle Boost and Double Boost, so you can choose anything from lift with no added size up to two extra cup sizes. They adhere securely to both your skin and clothing, helping to keep your chest in place while offering added volume through their unique padding. These inserts are also perfect for filling out your bust in certain styles of dresses, giving you a fuller, more sculpted shape.
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 a natural looking boost of about one cup size, Subtle 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. It holds the enhancers firmly in place so they can do their job.
Will they show through my clothing?
Not when they're worn with the right fabric. A snug, structured outfit holds them smoothly against your skin, so no one will know they're there.
Are the breast enhancer inserts reusable?
Yes! All our inserts are washable and reusable. Simply hand wash them gently and let them air dry to keep them in top condition for multiple 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.
