How to Measure Bra Size in India with CashKaro Bra Size Calculator? 

If you’re wondering how to find the right bra size for yourself, follow the steps below. Get a measuring tape and a mirror to check your size.

Bra Size Measurement

Step 1: Measure Band/Underbust Size  

  • Place the soft tape snugly around your ribcage, ensuring it’s neither too tight nor too loose. 
  • Ensure that the tape is on the same level on the front and the backside
  • If you get a decimal, pick the nearest whole number to it. E.g., If you get 31.5, pick 32 as your band size.  

Step 2: Measure Your Overbust/Cup Size  

  • Place the tape around the fullest part of your breasts while ensuring that the tape is wrapped straight and evenly around your bust.  
  • If the number is a decimal, round it off to the next whole number.  
  • Put both these measurements in CashKaro’s Bra Size Calculator to find your accurate bra size. 

Step 3: Check the Straps  

  • The straps should neither dig deep into your skin nor keep slipping sideways.  
  • If your straps keep falling off, you can try tightening them. If that doesn’t work, the bra is unsuitable for you.  

TIP: How to tell if my bra is of the right size and fit? 

  • Wear your bra on the loosest hook. You should be able to slip in two fingers underneath the band comfortably.
Bra Fit
  • The fit of the bra should be snug, meaning that it should support you comfortably. If you find it restricting or too loose, it might be an incorrect size as the band may be too small or tight for you. There should be no spillage, and the cups should support your breasts properly.
Snug Fit Bra
  • The straps should not fall off your shoulders and should rest comfortably without digging in.

How To Choose the Right Bra for Your Breast Shape?   

Whether online or offline, shopping for the perfect bra can be an exhausting experience altogether. Every woman has differently shaped breasts, so a style of bra that looks flattering on your friend might not work the same way for you. While you may be lured into buying trending bras that look beautiful on Instagram, they may not be the right fit for you. Let’s discuss some of the most common breast shapes and bras that would complement them.  

  • Round Shape: Women with rounder breasts have an evenly circular bosom with nipples pointing straight outwards. The breasts are full both at the top and bottom.

Bras for You: Since these breasts don’t need shaping or contouring, you can wear a basic t-shirt bra, balconette, and plunge-style bras.

  • Bell and Teardrop Shape: You have a bell or teardrop shape if your breasts are rounder at the bottom and slender on top, with nipples pointing at the fullest bottom.

Bras for You: You can choose a balconette bra or demi-cup with an underwire that will support your breasts and add a little volume on top.  

  • Asymmetric: Having one breast larger than the other is more common than you think.  

Bras for You: You can go for a t-shirt bra with light padding to make your breasts appear similar.
