Measuring your body: Use a soft tape measure directly against your body. Measure your waist at the narrowest point and your hips approximately 20 cm below your natural waist.
Compare to a favourite piece: Measure a similar garment you already own and love, then compare to our size guide for the most accurate fit.
Between sizes? We generally suggest sizing down as our clothing is designed to be flowy. Measurements may vary by 2–3 cm as each garment is measured by hand.

Grab a soft fabric tape measure. Stand naturally, feet together. Measure over underwear or a single lightweight layer for the most accurate results.
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.

Get In TouchCustomers rave about this comfortable, oversized smock dress with "amazing quality" fabric and pockets. It's versatile for casual or dressy occasions and "great for breastfeeding." Most love the flowy fit, though many recommend sizing down as it runs large. Some note length may shorten after washing and arm elastic can be tight.
Absolutely love this dress. I’m 168cm tall and usually size 16 and I got the s/m. The overall fit is perfect except I wish it was that bit longer in length so it doesn’t show my ankles. Gorgeous dress though! 💗
This dress is an absolute dream for mums. It’s unbelievably comfy, so easy to throw on, and somehow makes you look instantly put together in literally seconds. The fit is so flattering and it’s honestly such a gorgeous, stunning dress. Definitely a must have!
Beautiful dress so light weight and comfy
I have worn the dress repeatedly since I bought it. It’s comfortable and stylish and have many compliments on it since!
I love the fabric and feel of the dress. Lovely to wear & easy to feed in.
This dress is incredible quality. Super spacious especially around the tummy area. Cool and breezy but good coverage!
I'm Japanese and revert to Muslim.
+ I have my second baby and nursing.
it is so hard to find cotton clothes that covers the whole body and in the same time easy access to breast feed and cute.
I am so greatfull to find this dress!!!!!
only 1 suggestion is to have another botton on top
and it's little hard to breast feed when I sit down
specially right now my daughter is almost 8months and moves around!LOL
but 5stars cuz I love it!!
cant wait to go back to my country(Japan) and where all the dress I got from here!!

so true to size💕
I would also wear when I get pregnant with 3ed one✌️🤣
Excellent fit (I’m a size 16), lightweight material and stunning print!
Gorgeous dress!
I got this dress for myself and absolutely love it! It does run large. I have the SM and am typically a 12-14 in other brands. I wear this dress ALL THE TIME!!! I just repurchased this for a friend as she finds it hard to find clothing in her size. I got her the 3XL and I’m hoping it fits well. This is a dress that you will throw on and use time and time again! A must have staple for your wardrobe.
This dress makes me feel so beautiful, girly and comfortable all in one! The print is so beautiful, I just needed to buy it! The maxi Avalon dresses are definitely oversized, so size down if you want it to sit a little bit more fitted.
I can’t wait to get more of these in different colours/prints. It’s my favourite item in my wardrobe and most comfy!
The Avalon smock dress is so comfortable and versatile! It’s been perfect for breastfeeding and it’s such a flattering style. It makes me feel cozy but beautiful 💙
I had to have it tailored because my size wasn't available, but it was worth it. I loved the green gingham the moment I saw it. I wish they made long pants in this pattern too, i'm obsessed!!!
Amazing dress! I have the blue and caramel now and both are so beautiful. I’m reaching for these dresses endlessly! From the pockets to the flowy skirt, I’m always taken away at how stunning they feel and look on!
This dress is comfort and style wrapped up in one. Such an easy throw on option. And the pink/yellow colourway is my favourite!
Absolutely gorgeous candy pink colour and the white embroidery design is the perfect feminine pop! This Avalon maxi is a staple in my wardrobe and gets worn almost once a week! Lined so perfect for the cooler days and roomy!
I love love love this dress...it is perfectly oversized and soo pretty. I could have sized down in to a s/m as it does run fairly large, but appreciate the length! I will be buying more in every color!!!
