2021 Swimwear Trends

This annual article is based on our 2021 swimwear survey results paired with US sales trends over the past year. We had an incredible 21,209 respondents to our survey this year, which is an all time high.

Overview- 2021 Swimwear Trends

Are you ready for swimwear season 2021

Well 2020 is on its way out and 2021 is on its way in. 2020 represented a year when travel was cut short, the general population was locked down and frustrations were high. Interestingly when spring crept up, swimwear sales were crazy and there was an obvious swing in the desired trends most likely driven by beach, cottage and boat worshippers desperate to get out for some fun in the sun.

2021 Swimwear

Over the past few years, the cheeky bikinis, thongs and g-strings have seen a massive increase in popularity partnered with the trend for curvier women, but the lockdown has amplified this trend.

Even woman that would  wear a moderate one-piece swimsuit are now looking for higher thighs and plunging necklines. It seems the smaller the better for 2021.

Another trend we noticed was that many women spent their down time working out in the solitude of their homes. Home gym equipment sales hit an all-time high during the COVID lock-down and workout clothing was virtually nonexistent in both stores and online sales.

Further the trend continues for older woman who are working out regularly holding onto their youthful appearances desire a higher level of fashion in their swimwear styles partnered with again the more mature curvier figure is now becoming the mainstream desired female physique.

So without further ado, lets take a look at what the 2021 swim season has in store for beaches, cottages and boaters alike.

The chart below represents the general swimwear trends at a top level. this chart shows not only the trends over the past 6 years but which of the top general styles meaning bikinis, thongs, g-strings, tankinis and one piece swimsuit are trending for this coming year.

Trending graph summarizing 2021 general swimwear trends

From the data graph above we can see the sudden change in the bikinis, thongs and somewhat the g-sting styles. The general bikini has lost 7% of its ranking over the past year. As much as this trend has been ongoing for the past six years, a 7% drop is considered considerable over a twelve-month period. More importantly the thong bikini has taken a sudden leap of 13% in popularity which is a shocking surge in popularity over the same period last year. We also see a somewhat similar trend with the G-string adding 5% to their popularity but still nowhere near the thong.

In addition, both the tankini and the one-piece swimsuit have lost more traction this year with the tankini losing 5% and the one piece losing 6%.

Interestingly in the comment field for this question, we had a high number of respondents who mentioned both Tonga bikinis, Tonga one-piece swimsuits and thong one-piece swimsuits. Our analysts found this interesting simply because the Tonga has been mentioned in past years but not in the numbers that we are seeing this year. Note: As the year progresses, we may add the Tonga styles as part of this survey next year.

The obvious outcome of this portion of the survey is that the cheekier styles are in without a doubt but not only in the 18 to 25 year old categories but also in the 25 to 40 categories and in many cases nearing 50 year old’s. lets be honest, women are holding onto their girlish figures well into their mid to later years, combine this trend with the fact that the curvaceous figure has now become extremely desirable further expands the demand for the cheekier styles.


What is a Tonga

Tonga Definition: The Tonga style is very similar to a thong bikini or thong one piece swimsuit but offers ever so slightly more coverage. This would likely explain the increase in popularity as it is considered a cheeky style and a transition swimsuit to the thong.

Other than there is a slight increase for women in the younger age group, “18 to 25” years old wearing underwire bikini tops the bikini top trend has not really changed. It seams the focus is more on the fabric and sheer / see through levels than on style when it comes to bikini tops. Translucent bikini tops are definitely trending up.

Bikini Bottom Trends for 2021

Cheekier bikinis are in style for 2021

Heading into 2021, there was a definite jump in the cheekier styles of bikini bottoms. Maybe it was somewhat driven by the COVID lock-down and people were desperate to get out, only time will tell.

Overall there has been a trend towards the cheekier styles including Tonga’s, thongs and G-strings over the past five years, but heading into the upcoming year, they have taken a strong hold. Of course the full coverage and high thigh bikinis are still in the lead, but not by much. There is only a 3% differential between the thong and the full coverage bikini and if the trend continues into the following year, we just may see the thong take over first place. So for the bikini bottom style of the year, you can expect to see many more thongs and Tonga’s on the beaches this coming travel season and into the summer for 2021.

Sheer Bikini Top Trends for 2021

2021 brings more sheer swimwear styles

Another surprise heading into the coming fall and winter and into summer 2021 is the tolerance level for sheer and see through swimwear styles.

Similar to the thong bikini, the sheer styles are in style for sure. Over the past 5 years we have seen the not sheer styles drop from 80% down to 45% in 2020 and a further drop heading into 2021 at 26%, where as the sheer see through styles have seen a steady increase not only in acceptability but popularity from 2% in 2016 to 21% for 2021. Further the slightly sheer styles saw the most increase in popularity from 12% in 2016 to 28% heading into 2021.

2021 One Piece Swimwear Trends

When it comes to the one piece swimsuit we have always had an issue with survey participants completing this section of the survey yet this year, we had a whopping 87.3% completion rate of participants that started the survey completed this section. The best we have had previous to his year was 49.1%. that is almost a 38% increase in completion rate.

With the numbers seen below, there is not really any surprises. The full coverage swimsuit continues to loose traction where as the sexier versions including the styles with deeper plunging necklines, high cut thighs sheer versions and one piece thongs all gaining in popularity, but unlike the bikini trends, the one piece swimsuit demonstrates a steady transition.
