This chic black one-piece can be paired with any beach cover up, even being worn as a bodysuit to help you maximize your holiday wardrobe. The straps aren't adjustable however, so if you have a shorter torso, you may find the straps a bit too relaxed.

How to choose the best plus size swimwear

When it comes to selecting the best plus size swimwear, fabric and fit should reign supreme. If you already invest in the best bras for large busts, then you should follow a similar fit mentality when looking for the best plus size swimwear. 

Styles that have built-in bras, underwiring, or come in cup sizes will be among the best swimsuits for large busts, offering the best fit, while a halter neck style or a plus size swimsuit with adjustable straps will ensure you can easily give yourself some added uplift if necessary. 

Many of the best bra brands for fuller figures also have fantastic, curve-flattering swimwear lines and these brands will naturally make some of the most supportive swimwear when it comes to fit as they can draw on their experience from designing the best bras to ensure great coverage and lift.

When it comes to fabric, just like with the best plus size shapewear, you want to feel supported and sculpted. Opt for slightly thicker and heavier weight elastane and lycra and select for your regular size. Buying a size too small will pinch, go too big and you risk your swimsuit shifting in the water - not something any of us want.  

What is the best material for plus size swimsuits?

Polyester is the leading fabric when it comes to swimwear, both for main line and plus size iterations. This is because it is slightly quicker at drying and is less absorbent than Nylon. Polyester would usually be woven with something like Lycra for added stretch as you want a good amount of movement in your swimsuit, but you still want it to contour to your shape. 

What’s The Best Way To Know My Swimsuit Size?

Generally speaking swimwear sizes should correlate to your regular dress size. Alternatively if you are choosing a swimsuit specifically for greater bust support, opt for styles that come in bra sizes. 

As there is so much variation between brands, it is always best to know your hip, waist and bust measurements and compare them to sizing guides online to help you get the best fit. While swimwear does have some stretch, you don't want to find your swimsuit sagging, or pulling. 

What swimsuit stores have the best size range?

Swimsuit sizing varies greatly from store to store, but for plus size swimwear, a great place to start is with fashion brands you already know stock your dress size. Look to the best plus size clothing brands for extensive swim ranges, or alternatively check out brands that also cater for larger busts, as they often carry slightly larger brief sizes too. Examples include Simply Be, ASOS Curve and Good American, all of which usually cater for fuller figures. 

Do swimsuits get tighter or looser in the water?

Swimsuit material absorbs water when in the pull, making the fabric heavier due to the water weight. This can pull on the fabric making it looser in the water, if the suit isn't the right fit to start with. They will also lose stretch over time, as the elasticity goes, making them baggier and less contoured.
