Customer Reviews
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!
Love this lemon gingham top, it’s so fun! Great to wear with the matching shorts or pants but also fun with denim.
So comfy, so cute. Feel like I’m living my 80s mum/picnic fantasy

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.
