YOU DESERVE THE

PERFECT FIT

Our bikinis are designed with YOU in mind. Each piece combines support, security, and a cheeky touch to make you feel confident and comfortable.

Fit Tip: Your bikini should feel snug when you first try it on. This ensures that once wet, the fabric will stretch slightly, providing a comfortable and flattering fit.

Size Guidance: If you're between sizes, consider your preferred coverage. Opt for a smaller size for a more secure fit, or size up for additional coverage. Remember, swimwear fabrics stretch when wet, so a snug fit initially is ideal.

All measurements are in inches

If you're torn between sizes, we suggest sizing down for a snug fit—our swim fabrics stretch when wet, and this keeps your bikini secure and flattering, avoiding any unwanted sag.

Finding Your Bra Size

Measuring yourself can feel… ugh. But here’s the thing: these are just numbers. They don’t mean a single thing about you.

They’re just our cheat sheet to get you in a bikini that feels amazing, and lets you forget about everything except that next pool day!

Before we start you will need a few things:
A soft measuring tape, a mirror and your best fitting, least padded bra (no sport bras).

*If you are like most households and don't have a soft tape measure, use a string and hold it up to a rule

STEP ONE

MEASURE YOUR BUST

Measuring your bust to get your cup size:

Slide your measuring tape up your back, across your shoulder blades and across the fullest part of your bust (often this is over your nips).

Keeping the measuring tape straight across your back, hold the tape as loosely (without letting it droop) and take note of that measurement.

STEP TWO

MEASURE YOUR BAND

Wearing your best fitting bra and wrap the measuring tape straight around your back just under your bust (see photo).

Measure tight against your rib cage and note measurement.

*if using a string, take the part wrapped around you and hold that against a measuring tape/ruler to see how many inches it is

Calculating: If your measurement is an odd number, add 1, if it's an even number, add 2.

Ex: 35 inches rounds up to 36
Ex: 32 inches rounds up to 34

STEP THREE

CALCULATE YOUR CUP

Math time!
Subtract the Bust Size from the Band Size to calculate the Difference.

Band Size - Bust Size = Difference

Calculating the Difference
Ex: 39" bust - 34" band = 5" difference
Ex: 32" band - 35" bust = 3" difference

*The difference is used to find cup size

**Make sure you are rounding up the band size correctly according to Step 2

Refer to the graphic for a visual example.

STEP FOUR

MEASURE YOUR BAND

Use this graph to determine your cup size

Bra Size = Band + Cup Size

Example:
39" bust - 34" band = 5" difference

According to chart 5" difference is a DD cup

Therefore -
39" bust - 34" band = 34DD (5" difference)
