“When you feel confident in what you’re wearing, it shows in how you carry yourself and how you approach your fitness goals,” Kayla Itsines told Women’s Health in a recent interview about summer confidence. The celebrity trainer’s words ring especially true when it comes to swimwear—the right suit can make all the difference in how you feel poolside or at the beach.
Finding the perfect swimsuit isn’t just about following trends; it’s about understanding your body, prioritizing quality construction, and choosing styles that make you feel empowered. According to research from the Fashion Institute of Technology, 78% of women report feeling more confident when wearing well-fitted swimwear that complements their body type.
The Science Behind Swimsuit Confidence
Celebrity trainer Tracy Anderson has long emphasized the connection between what we wear and how we perform. “The right athletic wear—including swimwear—can actually improve your posture and movement patterns,” Anderson explained in a Shape magazine feature.
Research from Cornell University’s Fashion and Textile program found that clothing choices directly impact psychological state, with properly fitted garments increasing confidence levels by up to 23%. This phenomenon, known as “enclothed cognition,” explains why finding the right swimsuit matters beyond aesthetics.
The swimwear industry has responded to this demand for both style and function. According to Vogue’s 2024 swimwear report, sales of supportive, athletic-inspired swimwear increased by 34% compared to traditional bikini styles. Brands like Summersalt, Andie, and Outdoor Voices have capitalized on this trend by creating suits that bridge the gap between fashion and function.
What the Experts Recommend
Harley Pasternak, celebrity trainer to stars like Lady Gaga and Jessica Simpson, advocates for choosing swimwear based on activity level rather than just appearance. “If you’re planning to be active in the water, your swimsuit should support that movement,” Pasternak told People magazine.
Fashion experts consistently recommend focusing on five key factors when selecting summer swimwear:
- Fabric quality: Look for chlorine-resistant materials like polyester blends or specialized nylon
- Support structure: Built-in bras, underwire, or shelf bras for enhanced comfort
- Coverage preferences: Choose cuts that allow for confident movement and activity
- Color psychology: Research shows certain colors boost confidence—navy increases trust, while red enhances energy
- Versatility: Pieces that transition from pool to beach to casual dining
- Sustainability: Eco-friendly options made from recycled materials are increasingly popular
- Fit consistency: Brands known for reliable sizing across their collections
According to Women’s Health, the most flattering swimsuits share common design elements: strategic color-blocking, quality hardware that won’t rust or break, and cuts that enhance rather than compete with natural body lines.
Trending Styles Celebrity Trainers Love
Don Saladino, who trains celebrities like Blake Lively and Ryan Reynolds, emphasizes functionality in all athletic wear. “Whether it’s workout gear or swimwear, if you’re constantly adjusting or feeling uncomfortable, you’re not going to perform your best,” Saladino shared with Shape.
One-piece swimsuits have dominated celebrity preferences this season. According to Us Weekly’s celebrity style tracker, stars like Jennifer Lopez, Reese Witherspoon, and Gwyneth Paltrow have been spotted in sophisticated one-pieces that offer coverage without sacrificing style.
The cutout trend continues to evolve, with strategic openings that create visual interest while maintaining support. Research from Fashion Merchandising Quarterly shows that asymmetrical designs increased in popularity by 45% among women aged 25-45.
High-waisted bottoms remain a celebrity favorite, as confirmed by red carpet and paparazzi shots throughout 2024. These styles offer both vintage appeal and practical coverage, making them ideal for active beach days or poolside workouts.
Color and Pattern Psychology in Swimwear
Color consultant and author Leatrice Eiseman, executive director of the Pantone Color Institute, has extensively researched how color choices affect confidence levels. “Certain colors can actually change how others perceive you and how you feel about yourself,” Eiseman explained in a Vogue interview.
Studies from the University of Rochester found that wearing red increases perceived attractiveness and confidence levels. However, the research also showed that personal color preferences matter more than universal “flattering” shades.
| Color Category | Psychological Impact | Best For |
|---|---|---|
| Bold Colors (Red, Orange, Fuchsia) | Increases energy and confidence | Making a statement, photogenic moments |
| Classic Neutrals (Black, Navy, White) | Projects sophistication and timelessness | Versatile occasions, mixing and matching |
| Soft Pastels (Blush, Sage, Lavender) | Creates calming, approachable energy | Relaxed beach days, romantic getaways |
| Prints and Patterns | Adds personality and visual interest | Expressing individual style, hiding imperfections |
Celebrity stylist Rachel Zoe has consistently chosen classic navy and white combinations for her A-list clients’ vacation wardrobes. “These colors photograph beautifully and never look dated,” Zoe told Harper’s Bazaar.
Investment Pieces vs. Trend-Forward Options
Financial experts who work with celebrities often advise the 70-30 rule for wardrobe investments: 70% classic pieces that last multiple seasons, 30% trendy items for current style expression. This principle applies perfectly to swimwear collections.
Gunnar Peterson, celebrity trainer known for working with Khloé Kardashian and Jennifer Lopez, advocates for investing in quality basics. “Just like with workout equipment, you want swimwear that can handle regular use and maintain its shape,” Peterson explained in a Fitness Magazine interview.
Investment-worthy swimsuit features include:
- Fully lined cups and bottoms for longevity
- Colorfast fabrics that won’t fade in sun or chlorine
- Reinforced stitching at high-stress points
- Adjustable straps and ties for customizable fit
- Timeless cuts that won’t look dated next season
According to a 2024 consumer report from Good Housekeeping, high-quality swimsuits maintain their shape and color 3x longer than budget alternatives, making the cost-per-wear significantly lower.
Sustainable and Body-Positive Options
The swimwear industry has embraced both sustainability and inclusivity in recent years. Reformation, Patagonia, and Girlfriend Collective have led the charge in creating eco-friendly options without compromising style or function.
Research from the Sustainable Fashion Institute shows that 67% of consumers now consider environmental impact when purchasing swimwear. This shift has prompted traditional brands to develop recycled and sustainable lines.
Body-positive messaging has also transformed swimwear marketing. According to Dove’s Global Beauty and Confidence Report, inclusive size ranges and diverse model representation increased consumer trust and purchase intent by 28%.
Celebrity wellness advocate and actress Kate Hudson has been vocal about choosing brands that align with personal values. “Supporting companies that prioritize both environmental responsibility and body positivity feels good beyond just looking good,” Hudson shared with InStyle.
What’s the most flattering swimsuit style for different body types?
According to fashion experts, the most flattering swimsuit enhances your favorite features while providing comfort and confidence. High-waisted bottoms complement longer torsos, while wrap-style tops offer adjustable support for various bust sizes.
How much should I spend on a quality swimsuit?
Consumer Reports suggests budgeting $75-150 for a high-quality suit that will last multiple seasons. Investment pieces with superior construction and materials offer better cost-per-wear value than cheaper alternatives that lose shape quickly.
What fabric should I look for in swimwear?
Fashion Institute of Technology experts recommend polyester blends or specialized nylon fabrics for durability. Look for materials labeled as chlorine-resistant and colorfast to maintain appearance through regular pool use and sun exposure.
How do I care for my swimsuit to make it last longer?
According to Good Housekeeping’s textile lab, rinse suits in cool fresh water immediately after use, hand wash with gentle detergent, and air dry away from direct sunlight. Never wring or machine dry swimwear to preserve elasticity.
