    I just got my order for the CYA double-string bottom and Selva full X-back top in white fluff. I ordered sizes small and medium to see which I liked better. In clothing I generally take a small size, but in bikinis I prefer more bum and boob coverage, but was concerned that the medium would not fit. Well, first of all, I am absolutely crazy about the print! It is even prettier in real life! The small top and bottom definitely fit, but was more revealing. The medium, given the adjustability of the ties, is the cutest and most flattering suit I’ve ever put on and has the coverage that suits my comfort level! Best Bikini Ever!!!

    I’m 37 and was dreading buying swimsuits for this beach season with my active boys. I really didn’t want a mom suit! This is the cutest bottom I could ever imagine. I’m a 2 and the small was great. I’m online right now ordering another!

    How can you refer to this as a full-coverage design when the bottom third of the model’s butt is not covered by the swimsuit? (And you can bet if it doesn’t cover the model’s butt, it won’t cover mine.) This is the kind of stuff that makes me hate swimsuit shopping.

      Hi KC –

      Thank you for checking out MI OLA and letting us know what you think.
      Sorry that we are not meeting your expectations for bottom coverage. When I started this company, I had a strong stance against full coverage – only because the more fabric on your bum, the more likely that the bottom is to come down. The additional fabric acts as a “sail” in the water and moves more with the water.

      Then we listened to our clients and made this bottom. We call it our Full Double-String because – compared to our original Double-String Bottom – it’s a lot fuller. Thank goodness I have customers telling me what to do! This style became our BEST selling bottom.

      We are still a small company and we listen…. so I really appreciate your feedback. We introduce new styles every year, and perhaps we’ll better meet you expectations with our next new styles!

    Agree with above review. Disappointed that it doesn’t wrap around/underneath butt cheeks. That’s what stays put for me. And then I don’t feel like I have a wedgie all day. Support in the butt cheeks is the most flattering style for many women, and this is very depressing for us, as this is the style lately. Nobody wants to see this on me. I’d rather draw attention up, as well as be comfy.

    I LOVE this bottom! I am a curvy girl and this bottom made me feel very confident and comfy – it really does not budge!

    I love these bottoms! I’ve always found bikini bottoms to look dumpy on me. Usually the back goes up too high and theres excess material sagging at the bottom. These bottoms solve both those problems. The top is just high enough to cover my backside, and the ruched seam prevents the sagging. Just enough cheek coverage to make me feel comfortable. My bum never looked so good in a bathing suit! Ordering a second pair now!

    The name is super deceiving! It may be fuller coverage than your other suits, but it is not a full coverage bottom. I’d say it’s even a stretch to call it moderate coverage. I’m having such a hard time finding a suit I’m comfortable enough in to wear around people like my nephews and my dad – they do not need to see that much of my rear!

      Hi Joy –

      Happy Tuesday! Thank you so much for your feedback and sorry we’re not the perfect fit this time. We’ll certainly take your feedback into account when we’re developing our new styles.

      When I started MI OLA, I was strongly against full coverage bottoms, because they often cause suits to move more with the water (and off the body,) so the CYA is our most full-coverage at this time.

      Please email me at, and we’ll send you a prepaid return shipping label. (I couldn’t find this email address in our system.)

      Have a great day!

    I just got my CYA Double String bottom in the Pescadito color(mermaid scales). First impression i had was I LOVE this fabric and the print is AMAZING! I was excited to try on my new bikini!! (I also bought the Selva full back X top in the same material- LOVE LOVE LOVE)

    I’m 5’5 maybe 5’6 and I weigh 150 with measurements of 37-29-42, I’m busty and have ahhhmm a booty. So when i looked at the size of the bottoms I thought ohh boy, these aren’t “full coverage” and well they aren’t what i’m use to when I get full coverage from other places. It does look like more coverage on the model and I was a bit worried that was the case, the model has a small booty. I’m going to keep my bottoms and wear them proudly, even though I’m not covered as much as I’d like. They are more cheeky than full coverage.

    Over all I love my new bkini!!

    Would there be a possibility of making a bottom with more coverage in the rear in this side tie like this?

      Hi Misty –

      Thank you so much for your review!
      There is a possibility… there is always a possibility. Especially if there’s a need from our customers.
      Right now, we’re working on completely new styles, but I’ll keep your suggestion in mind.

      Now that I’m back up north, a lot of my friends are asking for the same type of coverage.

    I just received this in M with the Selva top in aloha mermaidin’ and was worried about the fit based on other reviews since I like to be more covered….but I was wrong. These make me look and feel great! I absolutely love this bottom and am glad I stepped out of my comfort zone. They do not move at all and as a 35 year old mother of 2 young and active daughters, I still feel secure in them. Thanks!

    I am in my 40s and am a mommy, so I always try to find full coverage suits for my behind – while I wouldn’t characterize this as full coverage (at least not at my age – it would be for the younger set), it looks amazing. I can’t believe how flattering it is. It stays on, but I found that I need one larger suit for the coverage I like and hanging out at the beach and a smaller one for actual surfing. I’m 5’10” and 150 lbs – I got a large for swimming and hanging and a medium for surf.
