Did you know there are three common body types according to biology? Learning a bit more about these body types could be a key component to figuring out which swimsuit is best for your own body. We're sure some of you already know what looks best, but if you'd like some additional support on how to choose a bathing suit for your body type, we've got you covered. 

What Are the Different Body Types?

In the worlds of biology and physiology, there's something called a somatotype. A somatotype explains how we as humans have a genetic physical predisposition to certain body shapes.  

These somatotypes are called ectomorph, mesomorph, and endomorph. 


An ectomorph has a slim and lean build, sometimes with a narrower frame, shoulders, and hips. Ectomorphs also typiclly have a quick metabolism and difficulty gaining weight or putting on muscle. They also tend to have a lower percentage of body fat on them. 

We like a flattering one-piece or a bikini with a stylish cover-up for an ectomorph that shows off their figure in an elegant way.


Mesomorphs are naturally muscular and have an athletic physique or appearance. They also tend to have a broader chest and shoulders and well-defined muscles. These types of people are able to gain muscle and lose fat relatively easily. 

We love an active bikini or a swim tank with swim shorts for a mesomorph.


Endomorphs have a softer or rounder shape and a wider frame. Therefore, it's easier for them to store fat more easily. Endomorphs often have a slower metabolism compared to ectomorphs and mesomorphs. However, they can still build muscle with proper training and nutrition.

We'd recommend a bathing suit with swim leggings or swim capris for endomorphs. 

It's important to recognize that these somatotypes are general classifications and that individual variation can and does exist. Many people may not fit perfectly into one category and may display characteristics of multiple. Additionally, lifestyle factors like diet, exercise, and genetics play significant roles in determining an individual's body composition.

What Factors to Consider Before Choosing a Swimsuit for Your Body

When buying a swimsuit as a woman, there are several important factors to consider to ensure that you find the right swimsuit that suits your body type, style and preferences. Here are some key factors to keep in mind:

Your Body Type

If you look online, you'll see women's body types as shapes like hourglass, pear, apple, rectangle, and inverted triangle. You can go off this body shape chart or pull from our body types above to get a better understanding of what would fit your body. 

Comfort Level 

Comfort should be a top priority for you - especially if you're going to be swimming and dong water activities in your swimsuit. Make sure you like the material and fit of the swimsuit you're going to choose. 


Consider how much coverage you want as well. Swimsuits come in various styles, from bikinis and tankinis to one-pieces. Choose a style that makes you feel confident and comfortable. If you prefer more coverage, look for suits with higher necklines, long sleeves, or full bottoms.


If you need extra support, especially in the bust area, look for swimsuits with built-in bras and adjustable straps. These features provide better support and ensure a comfortable fit.


Ensure that you are comfortable in the material your swimsuit is made out of and that you'll actually want to wear it. Find a swimsuit that has material that will hold up against saltwater and chlorine too so it lasts longer and won't fade.

Activity Level

Consider the activities you'll be doing while wearing your swimsuit. If you plan to take part in more active water sports, a sportier swimsuit with secure straps would be more suitable. For lounging by the pool, a more fashion-focused bathing suit would work.

Sun Protection

You will want to choose a bathing suit with a Ultraviolet Protection Factor (UPF) to keep your skin protected from the sun's UV rays.

What to Look Out for if You Want a More Modest Swimsuit

If you're looking for a more modest swimsuit for women, there are several factors to consider, including the following:

  • Full coverage. 
  • High necklines. 
  • Longer hemlines (swim dresses are a great example).
  • Longer sleeves. 
  • High-waisted bikinis. 
  • Tummy control. 
  • Adjustable straps. 

Remember that modesty is a personal choice, and what constitutes a modest swimsuit may vary from person to person. Ultimately, choose a swimsuit that aligns with your comfort level and style preferences.

What to Look Out for if You Want a More Active Swimsuit

If you're looking for a more active women's swimsuit, you'll want one that provides comfort, durability, and support for all things water sports. Here are some factors to consider when shopping for an active swimsuit:

  • Performance-oriented material. 
  • UPF rating. 
  • Stretch. 
  • Secure fit. 
  • Support. 
  • Coverage. 

Remember that the right active swimsuit for you may depend on your specific activity and preferences. Whether you're swimming, paddle boarding, playing beach volleyball, or engaging in other water-based activities, choose a swimsuit that allows you to move freely and comfortably.

What Sunscreen Should You Wear with Your Swimsuit?

The Skin Cancer Foundation recommends a broad-spectrum sunscreen (this means it protects you from UVA and UVB rays) with an SPF of at least 15 with proof of water resistance for daily use. If you're active, then the organization recommends an SPF of at least 30.

Fortunately, all of our sunscreen here at UV Skinz meets these requirements! Check out our favorites below. 

FAQs About Choosing Swimwear

Is it Better to Size Up or Down in Swimwear?

When it comes to sizing up or down in swimwear for women, it all depends on the type of fit you want as well as your comfort level. Do you like a tighter, more form fitting swimsuit or do you prefer a swimsuit that has a little more room?

Do keep in mind that swimwear can fade and get loose over time, so we'd recommend finding a swimsuit that fits well but not too tight or too loose. 

What Should You Look for When Purchasing UPF Swimwear?

You definitely want UPF swimwear with a high UPF rating of at least 50. This is what The Skin Cancer Foundation calls excellent coverage. 

Other factors to consider include breathability, fit, style, price, and function. If you're pretty active, then look for UPF swimwear that has the words "active" in it. If you're someone over 60 and looking for more modest swimwear, find a UPF bathing suit that offers more coverage and longer sleeves. 

What Bathing Suit Is Best for Tummy Control? 

Bathing suit bottoms that are high-waisted provide excellent tummy control. Whether you've just had a baby or prefer a more comfortable, high-waisted suit, opt for swim shorts or swim pants that sit right above your belly button. 

Remember you can always add swim shorts, swim leggings, or even board shorts to a one-piece bathing suit as well to provide more support. 

What Is the Most Slimming Style of Swimsuit?

When it comes to swimsuits, what's considered the "most slimming" type can vary depending on your individual body type, preferences, and comfort level. Generally speaking, a swimsuit in a solid dark color like black, dark red, navy blue, or magenta is more slimming. 

Also, ruching on a swimsuit provides a slimming look as well as swimsuits with built-in tummy control. 

High-waisted bikini bottoms or swim shorts can provide extra coverage and support for the midsection, making the waistline appear more defined and helping  create an hourglass shape.

Remember that the most important thing is to feel confident and comfortable in your swimsuit. Different styles and features may work better for different body types, so it's a good idea to try on various options and see what makes you feel your best.
