Size Guide

 

Please view our size guide keeping in mind that our swimwear is designed for minimal coverage, therefore, we don’t recommend for you go for a size smaller than what you would typically be.  Each of our swimwear pieces is made with super-soft fabric and seamless finishes to optimise comfort long after you have left the beach.

We understand that sometimes it is difficult to choose the perfect size online, so to make it a little easier we have created a 30 day exchange policy. Click here for more information on our exchange process.  

BIKINI BOTTOMS

Between two sizes? Your right style and size will also depend on how you want to wear them – showing more skin, or less; sunbathing or surfing. We would recommend not going for a size smaller than you would typically be.

How our bottoms fit will depend largely on your body type and how much coverage you would like when you wear them.

CHEEKYS, HYBRIDS + BRAZILIANS

CUT: The design of the front of our original bottoms are identical – the only difference is the cut coverage on the back. For the most coverage, choose our Cheekys. Our Hybrids are in between our Cheekys and Brazilians, and our Brazilians give the least coverage but the best tanlines.

They are designed to sit low on your hips so if you plan to wear them high, be aware that the sides may twist.

TIE-SIDES

CUT: The cut and bottom coverage of our Tie-Sides are similar to our Hybrids – less coverage than our Cheekys but more than our Brazilians.

Note: Our Tie-Sides have been designed to give you the option to wear them a little higher on your hips.

HIGHT CUTS

CUT: Our High Cuts are designed for those that love to wear their bikini bottoms high waisted. They provide similar bottom coverage to our Cheekys.

BIKINI TOPS

Your body attributes (such as breast size, hip-width, frame etc.) and personal preferences (showing more/less skin, wearing whilst active or sunbathing) can influence how our bikini top will or should fit and therefore allow you to choose which size is right for you. Each of our tops is made with the most luxurious swimwear material, designed to optimize comfort.

TRIANGLES

Between two sizes? Go for the larger size - our triangles are designed to minimise tanlines, therefore they provide minimal coverage.

		XSmall	Small	Medium	Large
		AA or A	B	C	D or E

 

FIT: Just like the classic triangle cut, our triangle style has adjustable neck and back straps. The triangles aren’t fixed which gives you the freedom to wear them just how you like.

BRALETTES

Between two sizes? Consider whether you like a bit of cleavage - if not, then we'd recommend going for the larger size.  Further, the band around your ribcage doesn't stretch as much as our other cuts - take into account how broad/narrow you are.

FIT: Our Bralettes have an adjustable back strap with three hook closures and adjustable shoulder straps to help you find a comfortable fit.

CROPS

Between two sizes? Our crops are designed for minimal tanlines so consider if you would like tighter straps – if not then we'd recommend going for the larger size of the two.

	EURO	60AA/60A/65AA	65A/65B/65C	70B/70C	75C/75D

 

FIT: To minimalise tanlines our Crop comes with spaghetti straps that do not offer adjustable hardware, however, they do stretch after a few wears in the water so keep this in mind.

SCOOPS

Between two sizes? Consider whether you like a bit of cleavage - if not, then we'd recommend going for the larger size.

	Country	XSmall	Small	Medium	Large
	AU/UK	6A/8AA/8A	8B/10A/10B	10C/12B/10D	12C/12D

	EURO	60B/65AA/65A	65B/70A/70B	70C/75B/70B	75C/75D

 

FIT: Our Scoop is one of our most supportive bikini tops that is designed for minimal tanlines at the back.

ONE PIECES

The most important thing here is to consider your torso height more than your size!  If you have a long torso you may need to size up by one or two sizes.  Our One Pieces aren't adjustable so they won't fit every shape.  If you want specific advice to you, send our team an email at support@arkswimwear.com with as much info as you can provide - including torso height and bust (band and cup).

	Country	XSmall	Small	Medium	Large
	AU/UK	6	8	10	12
	US/CAN	0-2	4	6	8
	EURO	32	34	36	38

 

FIT: Our One Piece has been designed to fit a body with even proportions. Please consider your body shape, bust size, and height when considering a size for our one piece.

 

Size Guide

Note: this is a size GUIDE, as we are all different shapes and sizes, and few of us are the same size across different brands.

Our bikinis are designed for minimal coverage, so we don’t recommend you go for a size smaller than you would typically be.

Likewise, our range has been designed to minimise tanlines. So, with the wrong tanlines, our bikinis can look more revealing than they are. Sometimes you need to get your tanlines right for our swimwear to look right.

Our super-soft fabric and seamless finishes optimise comfort long after you have left the beach!

If you have chosen the wrong size, no problem! We have a 14-day exchange policy, so click here for more information on our exchange process.

Bottoms

How our bottoms fit will depend largely on your body type – if you have narrow hips, a large booty, love handles, or even what time of the month it is!

Our bottoms are seamless to maximise comfort. They are designed to sit quite low so if you plan to wear them high on your hip, be aware the sides may twist.

Country	XSmall	Small	Medium	Large
AU/UK	6	8	10	12
US/CAN	0-2	4	6	8
EURO	32	34	36	38

Between two sizes? Your right style and size will also depend on how you want to wear them – showing more skin, or less; sunbathing or surfing. We would recommend not going for a size smaller than you would typically be.

Cuts: the design and cut of the front of our bottoms is identical – only the design and cut of the back changes. For the most coverage, choose the Cheekys. The Hybrid is somewhere in between, and the Brazilians give the least coverage and the best tanlines!

Tops

You know your body - if you have a small bust, broad shoulders or ribcage, how your bust goes around that-time-of-the-month... You also know how and where you are wanting to wear the bikini - if you like to show more skin or less; if you are planning to wear it by the pool, or in the surf. Your body attributes and personal preferences can influence how the bikini will or should fit and therefore what size is right for you.

If you have implants, the size you need will depend on a number of factors. If your surgery was recent, you may need a larger size than what your doctor recommended. Comfort is assured thanks to the super-soft fabrics and wire-free design.

Triangles

XSmall	Small	Medium	Large
AA or A	B	C	D or E

Between two sizes? Go for the larger size - our triangles are designed for minimal coverage; you don't need less coverage than that.

Fit: Our Triangles have been designed to minimise tanlines, so are fit for minimal coverage. Just like the classic triangle cut, ours have adjustable neck and back straps. The triangles aren’t fixed which gives you the freedom to wear them just how you like to! If you don’t like any side boob, add a size. If you have a small bust with broad shoulders, add a size.
