bra - how to measure

1. underbust

Stand with your arms resting by your side and ideally get someone else to measure you around your body, directly below the bust. Make sure the tape is right under your breasts, is straight all the way around and is as tight as possible. This is how the underband of the bra will fit, so the tape should be tight, but not uncomfortable. It’s best to do this measurement while you’re not wearing a bra, or you can do it wearing one, just be careful not to sit the tape over your bra or underwire.

2. overbust

Measure around the fullest part of your bust (usually over the nipple). This is best done while you’re wearing a bra. Hold the tape gently so that the tape is resting lightly on your body. Make sure that the tape measure is straight across your back, and sits parallel to the floor.

forgiving fit™ technology

At Rose & Thorne, we know that every woman’s body is different and that our bodies are constantly fluctuating. We also know that between 60-80% of women wear the wrong size bra. That’s why we created Forgiving Fit™ Technology. A design that gives you more comfort in your day to day lingerie without costing you more or compromising in style.

There are two main components to our Forgiving Fit™ Technology:

Introducing Band - Flex

Rose

The first thing our designers looked at was the fixed measurement – the band around your body, under your bust. Get this wrong and you either feel cut in half or lack any real support. Band-Flex uses a combination of patterns, fabric and construction to ensure the bra adjusts to your body and keeps you supported.

Rose

The other key ingredient of any bra is the cup size. If it’s too big, your breasts will abandon any hope of support, too small and two boobs can look like four. Our solution: the Cocoon-Cup, a shape that naturally curves around the breast for a flexible fit with the right amount of support. With Forgiving Fit™ you’ll be much more comfortable with as your body fluctuates or even if you’re a little out with your sizing.

Forgiving Fit’s™ two design innovations combined with our Five Iconic Shapes ensure you have the comfortable bras you deserve each and every day..
