Brandstory BONSJANS was born from a personal search for the perfect push-up bikini.
After struggling with ill-fitting, unreliable pads, Janske set out to create a bikini that offers effortless support, a natural lift, and a flattering shape — without the hassle.

Designed for women who want to feel confident, feminine, and comfortable, BONSJANS is your subtle, feel-good boost for every beach day.

Where are your products made?

Designed in the Netherlands, crafted in Portugal. All our bikinis and push-up pads are crafted in Portugal, in carefully selected, family-run ateliers.
We work closely with experienced artisans to ensure exceptional quality, attention to detail, and a refined finish in every piece.

Why Portugal?

We chose to produce in Portugal to work closely with highly experienced ateliers that specialize in swimwear craftsmanship. Their expertise allows us to ensure exceptional quality, attention to detail, and a refined finish in every piece.

Producing within the European Union is also a conscious choice. It allows us to keep our production chain closer to home, helping to reduce our environmental footprint through shorter transport distances.

In addition, working within the EU ensures:

• Strict production standards and regulations
• Fair working conditions
• Greater transparency throughout the production process

By combining craftsmanship with responsible production, we aim to create pieces that are made to last — both in quality and design.

Can I wear the tops with or without push-up pads?Yes. Our tops are designed to be worn both with and without push-up pads, allowing you to adjust your level of support and shape.
A subtle inner pocket lets you easily insert the pads whenever you want a little extra lift.

Are the fabrics sustainable?
All our pieces are made using fabrics from Estilmar’s ECOWAVE® line, which combines innovation with more responsible production methods. These fabrics:

• Use recycled and sustainable yarns, giving a second life to waste
• Are produced with reduced CO₂ emissions
• Are manufactured using 100% renewable energy
• Follow water-saving processes, significantly reducing water usage
• Support local, proximity-based production

By combining craftsmanship with consciously sourced materials, we aim to create pieces that are not only refined in design, but also more considered in the way they are made.

Are your swimsuits see-through?
Our swimsuits are double-lined to prevent any transparency. We personally tested each piece beforehand to ensure this isn’t an issue — we know how uncomfortable that can be.

Can I wear the bikini with or without push-up pads?
Yes. All our bikinis are designed to be worn both with and without push-up pads — depending on your preference.

How do the push-up pads work?
When you purchase our push-up pads, you’ll receive a set of 3 different thickness levels. This allows you to fully customize your fit and level of lift — from natural to more enhanced — depending on the occasion.

What makes your push-up pads different?
Our push-up pads are developed by our own engineers to deliver the perfect balance between comfort, functionality, and lift.
They are:

• Lightweight
• Water-resistant (they absorb little to no water)
• Finished with a soft suede backing, making them gentle on the skin — even when worn inside a bra

They’re designed to give you a customizable, natural-looking shape with the ultimate push.

Can I adjust the level of push-up?
Absolutely. You can easily switch between the different pad thicknesses to control how much lift you want at any moment.

What if my breasts are not the same size?
No problem. You can use different pad thicknesses on each side to create a more balanced, even look.

Do you have fitting guidelines? All our swimsuits, beachwear, and accessories are carefully checked before shipping.
We ask that you try on swimwear over your underwear. If this is not respected, we will not be able to accept a return.

How should I choose my size?
We recommend taking your usual size. To help you choose, please refer to our size guide.
If you need advice, feel free to contact us — we’re happy to help.

Are your swimsuits suitable for larger breasts?
Our swimsuits are designed with underwire support and double-lined fabrics to provide structure, shape, and comfort.

At the moment, our sizing goes up to size L. As a growing brand, we chose to start with this range to perfect our fit and designs. We’re continuously evolving and expanding our size range is something we’re open to in the future.

Support and fit can vary depending on personal preference and the specific style. If you’re unsure, feel free to reach out — we’re happy to help you find your best fit.

When will my order be shipped?
As we are launching soon, orders will be shipped starting from the 30th of March. After that, delivery takes approximately 2 till 3 business days.

What are the shipping costs?
Shipping costs are calculated at checkout. Orders over €100,- (NL & BE) qualify for free shipping.

Do you ship internationally?
Yes! We ship internationally. Shipping costs and delivery times vary depending on the destination.

Can I return my order?
Yes, you can return your order within 14 days, provided that items are unworn, in original condition, and with the hangtag still attached.

Can I exchange for a different size?
Yes, exchanges are possible as long as the desired size is still in stock.
Please ensure that items are unworn, in original condition, and returned with the hangtag attached.

Are there any exceptions?
Due to hygiene reasons, swimwear can only be returned if the hygiene sticker is still intact and the label is attached.

How should I care for my swimsuit?

We recommend rinsing your swimsuit thoroughly after each use and washing it by hand.
Avoid soaking for long periods, do not use hot water, and avoid mixing very different colors. We highly recommend you to not wash the pieces by machine, as it can damage the elastic fibers and the underwire.

Care instructions

– Remove the pads before washing
– Do not wash the pads, let them air dry only
– Hand wash only, maximum 30°C
– Do not machine wash
– Do not tumble dry
– Lay flat to dry, away from direct sunlight

By caring for your BONSJANS pieces with love, you help preserve their shape, color and quality for longer.

Treat your BONSJANS Beachwear with care — after all, it’s candy for your boobs.
