What is the All Day One Piece Swimsuit?

The All Day One Piece is a Fearless Swimwear one piece designed for all-day comfort and support. It features 360 degree power mesh compression that sculpts the tummy and cinches the waist, wire-free built-in bust support with adjustable sliders for A-F cups, and medium-to-full coverage. It is available with Magic Sizing so you can choose your top and bottom sizes independently. The fabric is ultra-matte luxe recycled swim fabric with a chlorine resistance rating of 4 out of 5, designed to feel like high quality activewear.

What cup sizes does the All Day One Piece support?

The All Day One Piece is designed to support A-F cup busts with wire-free built-in bust support and adjustable bust sliders so you can customise your lift. Customers with larger busts report incredible support both in and out of the water, and the adjustable straps allow you to dial in the fit for your specific proportions rather than settling for a one-size approach.

Does the All Day One Piece have Magic Sizing?

Yes. The All Day One Piece is available with Magic Sizing, which lets you choose different top and bottom sizes in a single swimsuit. This is particularly useful for pear shapes or anyone whose bust and hip measurements fall into different standard sizes. Magic Sizing is available across XS to 3X, covering Australian sizes 6 to 20.

How much compression does the All Day One Piece have?

The All Day One Piece features 360 degree power mesh compression that sculpts the tummy and delivers a held-in, supported feel from all angles. The compression is firm, smoothing and supportive - designed to feel like high quality activewear rather than restrictive swimwear. Customers consistently describe it as compressive yet comfortable, hugging you in all the right places without uncomfortable pressure. This is stronger shaping than the Adventure Suit, which offers medium compression.

What fabric is the All Day One Piece made from?

The All Day One Piece is made from ultra-matte luxe recycled swim fabric with a chlorine resistance rating of 4 out of 5. The fabric is firm, smoothing and supportive with a premium matte finish that customers describe as noticeably elevated compared to typical swimsuit fabrics. Multiple reviewers note the quality is refined enough to wear as a bodysuit with jeans or shorts for everyday wear beyond the beach.

What coverage does the All Day One Piece provide?

The All Day One Piece provides medium-to-full bum coverage designed to sit on the hip. There is a subtle side-bust show to the design. Straps are adjustable and can be worn straight or crossed at the back, giving you flexibility over fit and coverage. The suit is designed to stay in place during surfing, playing with children and active beach days without constant adjustment.

Is the All Day One Piece good for long torsos?

Yes. The All Day One Piece is available in a Long Torso version in red, black and blue, designed to give extra length through the body without pulling at the shoulders or riding up. Long torso styles are tested on the Fearless Fit Crew including women with genuinely long torsos. Magic Sizing is also available in the long torso version so you can address both torso length and size differences between bust and hips simultaneously.

Is the All Day One Piece good for postpartum bodies?

Yes. The All Day One Piece is one of the styles in the Fearless postpartum collection. The 360 degree power mesh compression smooths the tummy and supports post-pregnancy bodies without feeling restrictive. Customers who have had children report the suit delivers the rare experience of finally finding swimwear that actually fits their postpartum body. Magic Sizing also accommodates postpartum bodies where bust and hip proportions have changed after pregnancy.

Lauren

I’ve been hesitant on purchasing because of the price point but I am SO GLAD I did! The fit is wonderful (I ordered based on my measurements) and I feel comfortable and beautiful at the same time. I’m an almost-40 mom of 2 so finding something that checks both boxes is important to me. It’s such a great suit for moms without being a “mom swimsuit”. Can’t wait to wear it this summer!

Donna

Had to send back as was to big. Seamless return.

Post as anonymous

Easy to order, arrived promptly and even caught a sale!

Katie

Swimsuit was so comfortable and fit perfectly. The Royal Blue color is beautiful. I wore it all day on vacation and felt supported all day. I received multiple compliments from other women at the resort :)

Lucy

I can’t actually begin to describe what it feels like to follow a company from its first moments, share the ups and downs via Instagram, wait with baited breath while its owner shows us each sample as it arrives, receive my password to the very first line drop on site, then actually WEAR the swimsuit I’ve always dreamed of.
This label have DARED to challenge an entire industry’s idea of what we SHOULD look and feel like in our swimmers, and I am proud of them even though I’ve never met them! I’m a customer for life now, no going back, ever.
