How to Size

BRA SIZE MATTERS LADIES SO FIRST,
LET'S TAKE SOME MEASUREMENTS

First Measure Your Rib Band

Measuring_Image1_0220

Take a soft measuring tape and run the tape measure directly above your chest, under your armpits, and all the way around your back making sure it’s straight across. The measuring tape should be snug.

Write your size down. This is your band size. If you’re between sizes, a tip is to round up if you’re pregnant or newly postpartum or round down if you like a more snug fitting bra.

Next, Find Your Chest Measurement

Measuring the fullest part of your breasts, directly over your nipples. Again, run the measuring tape all the way around your body then press the measuring tape inwards, towards your chest, between your breasts.

Write this measurement down.

CALCULATE YOUR MEASUREMENTS

Now, simply take the rib band measurement and subtract your chest measurement from it. The remaining number is your cup size.

Example, you measured 38 for your band and 40 across your chest. 40 – 38 = 2 Your cup size is B. You would be a 38B

Cup Sizes: 1=A, 2=B, 3=C, 4=D, 5=DD, 6=DDD, 7=G, etc.

TIPS FOR PURCHASING A GOOD FITTING BRA

The best time to buy your pumping/nursing bra is when you’re pregnant between 20-24 weeks.

  • Your band size at these weeks, might be what you should expect your rib cage to be after you have your baby.
  • If you wait later into your pregnancy, like 34-38 weeks your rib cage should be significantly expanded throwing off how the bra will fit and feel after you have baby.

If you’re taller, your band size might not increase as much during your pregnancy.

  • This means your band on your bra will fit on the snug side towards the end of your pregnancy.

If you’re on the shorter side, your band size will increase more during your pregnancy because there isn’t as much room in the torso for baby to grow.

  • This means your band on your bra will fit very snug towards the end of your pregnancy.
  • You may even consider getting a cheap bra that fits comfortably during your last few weeks of pregnancy but don’t expect it to fit after having baby.

If you buy your pumping bra at the end of your pregnancy and it fits comfortably, it will more than likely be too big newly postpartum.

  • Rumina’s pumping bras need to fit properly in order to securely pump hands free.  A bra too big won’t hold the pumps well.
  • Please remember to keep your tags attached and the item in clean and in new condition. We can always exchange/refund if the item doesn’t fit.

Rumina’s sizing guide is a guide.  Because every woman’s body is different or at different stages of their pregnancy or postpartum when purchasing Rumina products, trying on the bra/tank for the right fit is essential.

  • Leave the tags on and try the item on to see if it’s the right fit.  As long as the tags are on the item and the item is free of deodorant, odors and milk stains, Rumina will exchange or return the item for a refund.
  • To ensure that the item stays in new condition consider using nursing pads to prevent any milk stains.

We recommend trying on the items BEFORE removing the tags. 

Rumina offers exchanges and returns on all products if tags are still attached and the item is free of deodorant, body odor, milk stains, and has not been washed. If you find that you leak milk throughout the day, we suggest putting a nursing pad between your breasts and the bra while you’re trying the item on.

For information on how to exchange or refund any Rumina products, please go to Rumina’s FAQ’s section for steps.
