The Fitter Reviews

For your band measurement, wear it like a bra band around your ribcage and slide it until you feel the tension that's right for you. For your bust measurement, wrap it around your bust the same way and find your fit. The built-in reading window shows your exact number for each measurement — then just check the chart to find your size.

A flat tape measure can't account for how your body actually feels — breathing, tissue compression, movement. The Fitter lets you test real support by taking a deep breath while wearing it, so your size is based on how it truly feels on your body, not just a number pulled tight against your skin.

Most of your bra's support — about 80% — comes from the band, not your shoulder straps. That means if your band isn't right, your shoulders end up doing work they were never meant to do. The Fitter is built around getting that one measurement exactly right, so you finally get the real support you deserve.

Pay attention to where The Fitter sits on your ribcage. The closer it stays to your breast root (the crease right under your bust) without slipping down, the more support and lift you'll get from the measurement — this is your sweet spot for structured, all-day wear. If it's sliding down away from that crease, you'll know that band is too loose to hold you properly.

Take a deep breath while wearing it. If it feels snug but you can still breathe freely, that's your comfort zone — the size you'll want for long days when you care more about ease than maximum lift. If it feels tight or restrictive on that breath, size up until it eases. You get to feel the difference yourself, instead of guessing which number is right.

Nope — that's the part The Fitter will handle for you. Once you've found your fit, The Fitter's conversion chart instantly gives you both a Support Size and a Comfort Size, so you always know exactly what to order, whatever the occasion.

Yes. If a brand runs tight, just go with your Comfort Size — it'll give you the extra ease you need. If a brand runs loose, go with your Support Size instead — it'll snug up the fit so it doesn't gape or slip. Either way, you'll have both numbers from The Fitter, no more guessing.

Absolutely — that's exactly why The Fitter exists. Bodies change, and a size from a few years ago rarely fits the same today. The Fitter lets you check your true size anytime, privately, at home, in seconds.
