The One - Black

This cosi misses out on a 5 star because of it’s length on my long torso. The support however is excellent, the cut beautiful and the make is quality. Definitely my favourite one piece swimsuit I have ever owned. I’ve never felt so stylish, well supported and confident at the beach.

Great fit

I have never been able to find a one piece that fits, has support and looks good until the one! So happy with this purchase, now if only the sun would come out again so I can wear it!

A Few hiccups but in the end ok

I really appreciated the concept of having the opportunity to take up to 5 pieces to try before buying. I did incur a few technical issues in trying to place the order but appreciated that someone got back to me promptly. Same issue again when it came to trying to to return the items I didn’t want - the system refused to print a return docket but this time I got no response to 2 x separate enquires on how to progress the return. In the end I just packed the items and hand wrote a note and sent back the unwanted items to the senders address on the original box since there was no phone number to ring on the website and no response to my questions. Having said all this the product I kept - The One - was a good fit around the bust - which is extraordinary based on my past experiences trying to find a costume that actual fits. The fit around the leg and bottom wasn’t as secure as I would of liked -not sure whether it was the sort of seam it was - but I decided that was a compromise I was prepared to accept for the sake of the top half fitting and looking flattering.

I cried

This is the only one piece I have EVER been able to fit my ladies in to. I cried as soon as I put it on. I have never felt so elegant and confident in a one piece that doesn’t look like it’s made for my grandma. THANK YOU

Best D+ swimsuit I’ve seen but plenty of room for improvement

The positives: It is a flattering swimsuit that manages to look sexy even as a one piece. The simple cut and colour are timeless which should give it wear over multiple seasons. The cons: Sizing is several sizes too small. I always buy 8E bras but had to size up to an 8FF so I wasn’t bulging out in the bust. The online fitting didn’t pick this up or recommend the correct size. When I tried to speak to Steph about exchanging the sizes it took hours between each response even when I responded immediately to her. This meant it took days to have s few questions answered rather than a less than 10mins conversation. On my first couple of wears I’ve noticed that the seam on the bust curls out and won’t sit flat which is disappointing when considering the price point. The swimsuit also rides up at the back which means continual readjusting is required if you don’t want the swimsuit to turn into a g-string style. Seams and folds in the bust lining are visible. The verdict: It’s a first to have a swimsuit fit so well on the bust and it really fills a gaping hole in the market. Some fit details such as the visible seams on the bust and seams that curl out need to be addressed, especially at this price point. As anyone with a larger bust will lament at the process of bra shopping unfortunately this is no different. The process would be so much better if it could be done in store! Overall the best swimsuit I’ve come across for larger busts but still has plenty room for improvement.

Hey Amelia, Thanks for your feedback! Our sizing is based off standard lingerie measurements but breasts are no science and different lingerie brands offer different sizing so there can be variations across all brands. Our fit experts do their best to respond to customers as quickly as they can and can only suggest a size based off the customers information given. Thanks for letting us know about the seams we are looking into it!
