Try these 3 easy steps to determine your bra size.
Find your size with our easy 3-step measurement, so that you can finally feel comfortable in a well-fitted bra.
Before You Begin
- Have a measuring tape, pen and paper ready
- You will also need to be in front of a mirror
- Wear a non-padded bra that reflects your true shape
- You’ll need to determine your rib band and cup size measurements in inches.
Step 1: Band Measurement
Measure your chest above your breasts - make sure the tape is around your back and under your armpits. Check in the mirror to ensure the measuring tape is parallel to the floor along your back. The tape should be snug around your body without any fingers underneath the tape. If you are in between band sizes, round up or down to the nearest even number. This will be your rib band size (34, 36 etc.).


Step 2: Bust Measurement
Measure around the fullest part of your breasts, over your nipple area. This is a looser measurement than the rib band measurement. While holding both ends of the tape with one hand at the side of your breast, use your free hand to press the measuring tape in between your breasts to your chest. Subtract your band size from your bust measurement. This is your cup size.
Step 3: Calculate Your Size

Do you know your Breast Shape?

Shallow Shaped Breasts
Breasts that are less full at the top of your cup and fuller at the bottom of your cup. Tissue density can range from soft to average. Moms with multiple children, women who have experienced drastic weight fluctuations or mature women tend to have shallow shaped breasts.

Balance Shaped Breasts
Breasts that are equally full at the top and the bottom of your cup. Tissue density is usually average to firm. Average shaped breasts are in proportion with your shoulders and torso width.
Recommended Bras: Body Silk Seamless, Original Nursing Bra, Plunge, Restore, Ballet.

Full Shaped Breasts
Breasts that are very full at the top of your cup. Breasts tend to sit narrow or forward on the body and are generally round. Tissue density is usually average to firm. Full shaped breasts tend to run larger when viewed in proportion with your shoulders and torso width. When fully engorged with breastmilk, most breast will be full shaped during that time.
Recommended Bras: Original Nursing Bra Full Cup, Original Nursing Bra Extended Cup, Original Pumping & Nursing Bra, Body Silk Seamless.

A good, comfortable nursing bra is a necessary staple in all every nursing mom’s wardrobes. You are going to be spending a lot of days (and nights) feeding your little one, especially in those early days/weeks, so you will want to make sure you have a bra that can support and comfort you, while you give all the love, and comfort and nourishment to your baby.

Selecting a bra for Everyday Non-Nursing
- If post-nursing, your breast density has changed due to pregnancy and breastfeeding, and breast shape is typically more shallow
- Breast growth experienced in pregnancy and nursing may reverse themselves over 3 months or so, once you stop nursing
- Rib cage is likely to reduce close to pre-pregnancy size, or may remain slightly larger than pre-pregnancy size
- If you haven’t been pregnant or nursing, breast size and shape may still fluctuate throughout our life for many reasons such as age, health, diet, medications, exercise etc.
- Measure yourself for a bra often to ensure a comfy and supportive fit
