Shopping for a slimming bathing suit often involves paying attention to material and silhouette, but don’t discount the importance of color and patterns. Contrast-trim swimsuits, for instance, create a snatched look, thanks to figure-flattering details that play around with proportions and draw the eye vertically. You also don’t need to go on an extensive hunt to find this style — Amazon is packed with plenty of options for one-piece wearers, bikini lovers and other kinds of beach goers.
If you’re used to wearing solid colors by the pool, this is an easy way to add some whimsy and fun to your waterside look without venturing too far from your comfort zone. Since it’s just the trim that pops against the base color, it adds just enough. A waist-defining optical illusion and a stylish, fashion-girl spin? We’re stocking up ASAP!
17 Slimming Contrast-Trim Swimsuits on Amazon
1. Our Favorite: With thick straps and an eye-catching V-neck that keeps the focus up high, this classic-style one-piece looks good on everyone. The contrast detailing across the stomach also works to define the waist, making this pick extra slimming.
2. Triangle Texture: Not only is this two-piece bathing suit textured, but the trim is in a triangle pattern for added interest. We love the O ring between the cups, too.
3. Unexpected Rainbow: This double-strap one-piece has just enough flair with a pink, orange, yellow, green and blue trim. Not only does the detailing add color, but since eyes are being drawn up and down, you’ll appear long and lean as you chill by the pool.
4. Modest Two-Piece: With adjustable straps on top and a high-waisted design on the bottom, you’ll feel well supported in this under-$40 bikini. It offers the best aspects of one-pieces and two-pieces.
5. Coverage, Please: The vertical ribbed detailing on this one-piece bathing suit creates an overall slimming effect. We appreciate the adjustable straps and not-too-cheeky bottom for beach-strutting confidence.
6. Almost a One-Piece: If you’re just getting comfortable rocking a two-piece, this high-waisted bathing suit will ease you in. The longer-length top nearly meets the bottom, so you’re showing just a touch of midsection.
7. Vintage Vibe: This retro-inspired one-piece swimsuit has thicker trim to give it that pin-up style. Reviewers confirmed that there is noticeable tummy control, too.
8. Really Ruffled: The ruffles along the neckline of this tie-strap one-piece give the simple design a feminine touch. Aside from that attention-grabbing pop of white, the same style also offers tummy control, so you’ll feel smooth and secure in the sun.
9. Complimentary Crossover: This contrast-trim bikini pick has crossover, V-shaped bottoms for an ultra-slimming effect. The crisscross adjustable straps up top will also keep bigger-chested ladies super supported.
10. Buttoned Beauty: We bet you’ve never worn a swimsuit with buttons on it — but it’s worth trying in 2026! The added bonus is that it can double as a top and won’t look out of place when styled with shorts at a seaside lunch.
11. Quirky Color: You’ll get the best of both worlds in this V-neck tankini, which offers the convenience of two pieces but the coverage of a one-piece. We like how the trim isn’t a single solid color either, giving it a ’90s vibe.
12. Bandeau Babe: This high-waisted bikini has a bandeau top with adjustable straps, allowing you to get the fit just right. However, the real star of the show is the contrast trim that sits under the bust, helping to define smaller chests and create an instantly sexy look.
13. Lively Leopard: If you’re not afraid of making a statement, this animal-print one-piece swimsuit is for you. The contrast trim makes it seem more polished than wild, and the two horizontal stripes across the waist create a flattering cinched-in effect.
14. Striking Stripes: With thin vertical stripes throughout, this under-$40 one-piece swimsuit helps elongate your torso and balance out your shape. The easy black trim gives the pattern a more elevated feel while still looking youthful.
15. One-Shoulder Wonder: You may own a one-shoulder dress, but what about a one-shoulder bathing suit? This two-piece still feels supportive, thanks to its thoughtful fit and high-waisted bottoms.
16. No Bad Angles: Bye, ordinary black bikinis! Between the colorful contrast trim and bold stitching on the bottoms, this $33 Amazon find is the definition of flattering fun. You’ll also love showing off the unique crisscross design on the back of the top.
17. Must-Have Monokini: If you’re looking for a standout staple, you’ve found it in this cool, black-and-white monokini. The design is the best of both worlds, and those cutouts sneakily make your midsection look smaller and more defined.
