The Best Bikinis for Bigger Busts (and Smaller Backs)
Finding bikinis that actually work for a fuller bust without compromising on comfort, support, or style? We get it, it's a minefield. At Zigi Swim, we design with real women in mind. That means thinking beyond the typical fit models and creating swimwear that supports where it needs to and flatters where it matters, especially for those with a bigger bust and smaller back.
Here's how our designs help solve the most common issues we’ve heard (and personally experienced), and why our bikinis are loved by women with fuller chests:
Underwire for Lift (That Doesn’t Dig In)
We knew from day one that support was non-negotiable, and we weren’t about to compromise on comfort either. That’s why we created two underwired bikini tops, the Solero and the Calippo. They’re designed to:
-
Offer genuine lift and shape, without flattening or gaping.
-
Sit smoothly against the body with no digging or red marks.
-
Flatter both fuller busts and smaller frames by offering firm but flexible sizing.
Underwired bikini tops are a game-changer if you’ve struggled with swimwear in the past. They give the same structure as a supportive bra but are still soft and breathable for all-day wear.
Thoughtfully Designed Halter Neck (With Thick Ties)
The Tango Top is our take on a classic halter bikini top, but redesigned to solve two of the biggest pain points:
-
Neck strain from thin straps
-
Boobs being squashed or slipping out
We used wide underbands and wide ties to evenly distribute weight and avoid that dreaded neck ache. Plus, we added darts in the cups so there’s enough space and shape for a fuller chest, no squashing, no weird gaps.
Fabric Details That Matter
Each top is made with premium Italian ECONYL®, chosen for its supportive structure and buttery-soft feel. It hugs the body in all the right ways and gives that ‘held in’ feel, even for DD+ swimwear sizes.
Custom Fit for Small Backs, Big Busts
We skipped the one-size-fits-all approach. Here’s how we tailored our designs to work for small backs with large busts:
-
Adjustable back ties on all tops so your bikini fits your back perfectly
-
Adjustable straps on most our tops so you can control your level of support
-
Wide underbands that hold everything in without riding up
-
Darted and shaped cups for natural lift and a rounded fit
What’s Next?
We’re always learning, fitting, and tweaking. With every production batch, we gather real customer feedback and fit notes from our models and community. We’re planning to:
-
Expand our swimwear size range
-
Fine-tune shapes to give even better bust support and second-skin feel
-
Continue testing fits on a variety of body types, not just standard sizes
Because supportive swimwear for big busts shouldn’t be an afterthought, it should be the standard.
Final Thoughts
Whether you're a 30A or a 34E, or just tired of bikini tops that don’t hold up (literally), we’re here to change that. Zigi Swim is about feeling good, looking incredible, and making swimwear that actually adjusts to your body and fits like a glove.
PS. Given that we are a very new small business, please forgive us if our size range does not yet cater towards your body type. It is at the forefront of our plans to expand our size range as we grow and when funds allow, so watch this space!
