Sleep Comfort Starts with the Perfect Fit

Our Sleep Bras are designed for sensitive breasts and menopause-related changes. Finding your size is the first step to a more restful night.

Two Simple Measurements

All you need is a soft tape measure and two numbers.

Step 1. Measure your Underbust

Place the tape just under your bust, level and snug (not tight). Note the measurement in inches.

Tip : Breathe out naturally to get your most accurate "relaxed" measurement.

Step 3. Determine Your Cup Size

To find your cup, calculate the difference between your Full Bust and your Underbust measurements.

The calculation : Full Bust - Underbust = Cup Difference

Example: If your underbust is 36" and your full bust is 39", that's a 3" difference, so you're around a C cup.

Step 4. Determine Your Band Size
Use your snug underbust measurement.

Example: If your underbust is 31" and your cup is C, you're a 36C.

Still Unsure?

What if I’m between sizes?

We always recommend Sizing Up for the ultimate comfort experience.

Example : If you hesitate between a 38A and a 38B, choose a 38C. This provides a "Relaxed Fit" that accommodates bloating and prevents any digging in.

I have a Fuller Bust (E, F, G cups). Will this support me?

Yes! Our specialized "Fuller Bust" range is engineered to provide gentle, wire-free support. While it is not a high-impact sports bra, it provides the gentle stability our DD++ testers rave about, allowing you to settle into a deep, uninterrupted sleep.

My weight fluctuates during the month. Which size should I choose?

Our ultra-stretch fabric is designed specifically for this. Choose the size that fits your "fullest" day. Because it's unpadded, the bra will simply follow your shape on smaller days without gaping.

What if one breast is larger than the other?

Always fit for your larger breast. Our soft fabric will naturally adapt to the smaller side for a seamless look.

What if I still get the size wrong?

No stress. We offer a 60-day risk-free guarantee. If it doesn't feel like a second skin, contact us for a full refund.
