A lovely swimsuit. It is very flattering. I love the ruching across the tummy and the twist front. I also love the high back. Very happy with my purchase.

I recently purchased the Plains Twist Front Tankini in navy blue ( called night sky ) I love it! I rang the store first to ask a few questions and the sales assistant was very friendly and helpful. I ordered online and it arrived promptly and is exactly the colour in the picture ( was to match a bikini bottom that I already had ) the quality is great and fit is perfect. Very flattering- just what I wanted . Highly recommend Swimwear Galore. Thanks so much

Absolutely love this swimsuit!

I absolutely love the eco essentials one piece swimsuit! At first I was worried about getting the wrong size because according to the size chart I am between a US 6 & 8. I opted to purchase US 6 and it fits well, but it's a little lose around the bust area, so I am glad that this swimsuit has adjustable straps.

Best fitting swimsuit I've had in years!
22 July 2022

In the past I've purchased a size 10 swimsuit as I am a D cup, but could wear a size 6 on the bottom, so the suits have always been a big long and bagged a bit. I read a review on this suit by someone near to my height and weight, and they mentioned the top was way too big for them. The stylist said it ran large, so size down. I ordered an 8 and it's a perfect fit, I am so happy I think I will order in another color.

Black one piece twist front
11 October 2023

Great design. This is my 2nd twist front one piece. Only issue with both is one leg has been bigger which makes it ride up. Maybe just my bad luck but love the twist top

Cute suit and nice navy color but….
11 February 2023

I wanted to like this bathing suit. It was the first time ordering this brand. Unfortunately, the rear of the suit kept riding up when I tried it on. I can wear another name brand of this style without that problem. I liked the navy color and it fit other than this issue. I’m 5’, 112 lb and ordered the size 6.

Excellent

Very flattering. True to size. If there were one thing I’d change, it would be a very slightly better fit for my behind. The elastic may be ever so slightly lose. I’m concerned about it riding up. I’m being very picky though. This wouldn’t be an issue at all, but I’m 66. I’m 5’ 1” 107 lbs and got size 4. It might be it’s a tiny bit snug, but I didn’t want it too lose once wet or too big on top. Excellent suit. Excellent quality and super fast shipping.

Great swimsuit, too little bottom coverage
6 May 2022

I was sad to return this swimsuit. It is made well - light fabric, stylish, beautiful color (navy blue). However, the coverage for bottom is not enough at all. Sea Level makes good swimsuits. I wish they offer more options for swim dress - more colors other than black, more styles other than what I have seen/owned last few years. I am relatively small figured and ordered size 4 which fit me.

Perfect Fit
24 May 2023

This suit fits like a dream. I have a 34G bust so I wasn’t sure exactly how well it would fit but it’s exactly what I was looking for. It’s a bit snug in the top but at least I know it’s secure, I don’t feel the need to size up. Definitely will order another color as well.

It’s made well and the color is perfect for my matching printed bottoms. It’s a little snug so I’m going to try wearing it over a tank top around the house to see if it will stretch a little. I am in the process of losing 5 lbs which will help.
