The Three Measurements That Matter
Place the tape close under the armhole at the fullest part of your bust. Measure from side seam, around and back to the same side seam.
Keep the tape parallel to the floor — snug but not tight.
Measure at the narrowest point — usually 2–3 cm above your belly button. Place the tape from side seam, around and back.
Exhale naturally before taking the measurement.
Place the tape approximately 20 cm below your natural waistline at the fullest part of your hips. Measure all the way around.
Stand with feet together for the most accurate result.

Customers praised this shirt for its comfortable, breathable fabric and vibrant Wild Hearts print. Many said "love, love, love" and appreciated the thoughtful tie design. The shirt runs very large with an oversized fit. Several customers noted they needed to size down, though some enjoyed the roomy look. Great quality fabric and versatile styling options.
I am so happy I got my hands on the red crepe Billie top. It’s so lovely on, the material is a dream and the way it drapes is magic.
5 weeks postpartum and have been living in this shirt. So flattering and easy access for feeding. Have gotten so many compliments on it too. Feels nice to be able to easily get dressed and feel confident!
Highly recommend the clothing is so comfortable, so stunning, worth absolutely every cent. So friendly to breastfeeding mamas giving us the opportunity to look fashionable rather than daggy and boring whilst still having easy access to feed our children. Love, love, love. Will definitely be purchasing more! Would recommend sizing down though as they can be very generous in sizing 🤍✨
I love this shirt it’s the perfect oversized shirt!!!
I purchased this in the lead up to Christmas in 2025 and boy has it got its use! Such a vibrant colour, really comfy, cool material and the breastfeeding access has been a tremendous help. This has paid its self off already in use! Very generous and oversized fit- as this was my first Billie purchase I ordered the S/M but next time would like to size down to the XS knowing how oversized it is.
I've gotten so many compliments when wearing this. You can absolutely wear it without having something on underneath, but I love it half-tied over a little singlet. One of my fave purchases this year, absolutely love. You do need to be careful though, the fabric can stag a little.
Obsessed! Love this material,it'seven prettier in real life!
I fell in love with this print when I saw it and bought the whole set!! The design is so thoughtful, the ties are carefully positioned so that you can completely close the front if you prefer which I really appreciate in a tie up top. Great job TLC! Would definitely buy more prints! 🩷
This outfit looks so cute! As a loose fitting, comfortable ensemble - I’ve worn it to brunch, out for coffee and out to dinner with heels! Bright, fun and so many compliments.
I had held off on getting tops etc but couldn’t resist this one and the colour! So glad I bought it - I’ve worn it 3 times since I received it and need more in other colours now ❤️🫶🏻 So comfy, light, and can dress up or down.
I purchased the Billie shirt and Matilda shorts from the wild hearts collection and I’m obsessed! I went with M/L, could have got a S/M in the shirt but I love the oversized look and makes me feel super comfy. The shorts however are true to size :) xx
I really love the cut of this shirt but it definitely runs large
Beautiful shirt
So comfortable goes with anything
Love this shirt. Obviously feeding friendly and would be great for maternity too. Very roomy so I would go normal size or even size down one. Looks fantastic with a slim skirt or jeans/pants. Material creases but I iron it and looks perfect. Fantastic quality and know I will get a lot of wear out of it.
Gorgeous top! Flattering style and perfect in the set
I really love Both it’s a very oversized so I recommend downsizing but the are so comfortable I can’t get enough of them
Love my Billie Shirt in White! Can mix and match with all my favourite Lullaby Club pieces.
Love! Oversized look that can be dressed up or down.
I wanted to like this, but it was super over sized. Fabric and cut are nice though.
