Bra Size Calculator
Do you actually hate bras, or are you just wearing the wrong size?
Research shows that nearly 80% of women wear the wrong bra size. Imagine wearing shoes that are two sizes too small—uncomfortable, right? That’s exactly how your body feels when your bra doesn’t fit right.
While no at-home method is perfect, this measuring system gets you pretty close! All you need is a measuring tape, a non-padded bra, and a few minutes.
What many women don’t realize is that bra size changes over time. Weight fluctuations, exercise, pregnancy, or simply aging can shift your size—so if your bra fit at 16, it may not at 26.
We’re here to help. Our bra size calculator makes it simple. Just follow the steps below and find your ideal fit—because comfort starts underneath.
Bra Size Calculator
Step 1: Measure Your Underbust (Band Size)
Wear a regular (non-padded) bra. Stand straight, relax your arms, and breathe out. Wrap the tape measure around your ribcage, just under the bust. Hold it snug but not tight. This gives your band size.
Step 2: Measure Your Overbust (Cup Size)
Now measure around the fullest part of your bust, keeping the tape relaxed—not too tight. This gives your bust measurement.
Enter both values into our calculator to find your perfect size.
Have you been suffering from back problems? Constant headaches? Are adults always criticizing your problematic posture? Does the phrase bra size calculator sound completely foreign to you? The problem may not be you – just your bra size! Research shows that 80% women today are wearing the wrong bra size, even though information about measuring yourself has become far more accessible about the internet. And wearing the wrong style of bra can be terrible for your health.
What most people don’t seem to know is that even if you were wearing the perfect bra size six months ago, it could be totally wrong for you now. Things like losing or gaining weight, exercising, nursing and age can massively alter your bra size, making it necessary for you to refresh your bra wardrobe.
Moreover, wash and wear means bras wear out after some time. The elasticity wears out after a while, which makes the straps and band size loser than they were before. But in Pakistan especially, getting good information in-store guidance about proper sizing and even buying the correct size can be a total nightmare! That’s why Losha was created so that women can help women find the right lingerie for them.
Wearing the right bra makes all the difference. It supports you, shapes you, and most importantly—it makes you feel good. And that’s what Mistario is all about. 💖
