Let customers speak for us
Honestly, coming from a girl who has tried about 20 different swim brands, this has to be the BEST swimsuit I’ve ever tried on. It’s so flattering. I’ve never felt more confident or comfortable in a bikini, and I’m in no way overexaggerating either. It’s definitely a bit pricey, but if you’ve been thinking about it for a while like I was because I’ve known about this brand since 2024 and had been debating it I finally pulled the trigger, and I have no regrets. Best purchase ever!! Also, the quality is amazing! It’s buttery soft. If I’m ever thinking about getting more swimwear, this is the brand I’ll think of first. Also, this is the first brand I’ve ever taken the time to come back and write a review for. :)
Came in just in time for my vacation so excited to wear!! Forever loyal to sienna swim. Literally perfect bikinis that make me feel confident in my body no matter what style I buy!
Love this top! The pattern is so cute and fabric quality is a lot nicer compared to other brands I have.
Love this razor! I’m so glad I changed to a safety razor! I should’ve done it sooner
I got the Small bottoms and a large top originally. The large top was a bit too big on me but siennaswim was so kind and made it so simple to make a size exchange. Overall obsessed with the colors and fit of this swimsuit <3
Absolutely love this top!!! It’s sexy but also so functional. I was able to jump into the water without a care. Keep in mind I am a 38DD!!! Highly recommend.
I love my bathing suit so much! I absolutely need more !!
I love love love this bikini. I would size down for more of a cheeky wear but it’s one of my fav bikinis.
Fit amazing! Not too cheeky and the color is amazing! Will buy again
So so cute. The band is so nice and makes me feel secure. I ordered a medium but should have ordered a small but I still love it!!
Love this print love this top!! Fits beautifully
Cutest bikini bottoms I have ever worn!! For reference I am 5’6 and 125 lbs the small fits perfect.
Loveeee the fit very great, & costumer service was 10/10
I absolutely adore this swimsuit. The color ( cherry wine) is stunning & what I love most is the fit. There are adjustable straps on the hips and the shoulders. The cut of the front also gives a skinny waist illusion!!!!! Perfect cheekiness on the bottom too, I don’t feel exposed in this bikini but I do feel sexy and comfortable. 10/10!!!!!! Plus you get a little travel/wash bag included!
This one piece is my favourite bikini or once piece I’ve ever put on in my life. I’m extremely insecure and it honestly makes me feel so confident. Could not recommend any more! Love love love!
