Why should I wear Maternity & Nursing Bras?

Perfectly fitted maternity and nursing bras will be your saviour during pregnancy and nursing your baby.

All our bras feature nursing access and are suitable to wear from the 1st trimester all the way through to breastfeeding.

Be prepared and pack nursing bras in your hospital bag! Well fitting maternity and nursing bras are specifically designed to suit your shape during pregnancy and post-birth. Supportive bras will help to protect and lift your breasts, which in turn improves your back posture.

Here are 4 reasons why you should invest in good quality maternity & nursing bras:

  • Our maternity and nursing bras feature soft cups and extended rows of hooks and eyes (depending on the style of bra). This allows for more room for the diaphragm to expand during the months of pregnancy.
  • Wider bra straps ensure maximum support as your breasts become heavier, which would help support your back too!

  • The skin and tissue around your breasts are increasingly sensitive during pregnancy and post birth, so it is essential that you invest in good quality nursing bras that are gentle on your skin. Our maternity and nursing bras feature soft cotton lining for sensitive nipples during breastfeeding.

  • Easy nursing access is key! Choose between side sling (pull down access) or one-handed nursing clips to suit you.

Maternity Bra Size Guide

When should I start wearing Maternity & Nursing Bras?

As your weight and size changes during pregnancy, we recommend that you are measured and fitted for a bra throughout the pregnancy at least at 12-14 weeks, then a follow up fitting at 28 weeks.

To estimate what size nursing bra you'll need, you could take your measurement at 28 weeks and add 1-2 additional cup sizes. However, we would strongly recommend that you are fitted again 4 weeks after birth to ensure you have the best fitting nursing bra after your milk comes in.

Pro Tip:  Every pregnancy is different, but generally women find their bra size will increase by 1-2 cups sizes and 1-2 band sizes compared to their pre pregnancy size. After birth, once your milk comes in, you'd normally find that your cup size will increase by one additional cup size.

After 8 weeks of nursing, your band size is likely to decrease to your pre-pregnancy size. Don't worry - all of our bras come with extended rows of hook and eyes so you can easily adjust your size.

How should I measure my Bra Size?

Please see below measurement guidelines to determine your best Mayarya bra size.

  • Find your band size. Pull the tape measure around your rib cage underneath your breasts, placing it just under your bust at the front and making sure the tape measure is flat and straight across your back. Pull the tape tight around your rib cage and measure in centimeters:

  • Find your CUP size. Measure across the fullest part of your bust. Try to keep the tape measure nice and horizontal all the way round and measure in centimeters:

How can I tell if I'm Wearing the Correct Bra Size?

When you are fitted for a nursing bra, it should fit you on the middle hooks and the strap adjusters should have enough space to be repositioned to loosen throughout pregnancy. You should be able to sit two fingers under the band of your bra to ensure enough room for growth.

Your hand should be able to fit inside the cup to allow for space for breast pads.

How does Mayarya sizing work?

Mayarya follows international sizing standard. We take every effort to keep our sizing true and consistent and we want you to be able to wear the same size across all garment types in Mayarya. However, there will be occasional variations in the fit of some products depending on the style and fabric.

How does the size guide work?

The first step to determine which size to buy is by measuring your body size. Before you start measuring, remember to use non-stretchable tape and to keep the tape close to your body without depressing it. We aligned our products to the body measurements of the International Sizing Chart.

  • For Tops and Dresses, please measure your bust. Wrap the measuring tape around the fullest part of your chest (at nipple level).
  • For Bottoms, please measure your under belly or under hip. Wrap the measuring tape around the fullest part of your hips and just below your bump.

Please see our 'Mayarya Clothing Size Guide' below for more details:

  • CM
  • INCH

Please Note:

  • Our measurements indicate the maximum size within a range. For example, if your bust measurement is 89cm (35 inch), and under belly measurement is 95cm (37 1/2 inch), then you would wear a size S
  • Our model's average measurements during pregnancy: Waist (98cm / 38.5 inch) - Bust (90cm / 35.4 inch) - Hip (95cm / 37.4 inch) - Height (175cm / 5'8 inch)
  • Our model's average measurements not pregnant: Waist (68cm / 26.8 inch) - Bust (90cm / 35.4 inch) - Hip (95cm / 37.4 inch) - Height (175cm / 5'8 inch)
  • Our model wears size S for tops, dresses and bottoms



Bottoms are one of the first items you realize your belly started growing! At Mayarya, we have under belly and over belly styles to accommodate your style and comfort needs.

Under Belly Pants, Treggings and Leggings

They sit below your growing bump and are particularly great during warmer seasons as it means less layers for your bump. A great solution for women with very sensitive skin as it does not cover your belly. Mayarya's under the belly pants look much like regular pants with stretchy, elasticized waistband so you can continue wearing them post-pregnancy too!

Over Belly Pants and Leggings

They are particularly great if you want some support around your belly. We choose breathable and stretchy fabric so it will not restrict the growth of your baby. You can fold them down during the early stage of pregnancy, roll up during 2nd and 3rd trimesters and roll/fold them down post-pregnancy.

Over Belly Treggings
Front Twisted Maternity and Nursing Dress



Our dresses and tops are designed for both pregnant and non-pregnant women in mind so you can wear them seamlessly post-pregnancy.

You can select your size according to your pre-pregnancy size since our clothes are designed to fit from your first trimester to your third trimester. 

Our smart design allows more room around your belly during pregnancy but falls down nicely on your body after pregnancy.

If you have gained more than the average pregnancy weight according to your doctor, you could go one size up from your pre-pregnancy size. If you are between two sizes, we recommend you pick the larger of two sizes.
