Not your standard fit. This smock is all about volume. Want maximum floaty comfort? Go with your usual size. Prefer less drama? Size down 1–2 sizes. The key thing to check is length, as that will help you decide which vibe you’ll love most.

Why You’ll Love It

She’s floaty. She’s dramatic (in the best way). She’s about to become the most versatile piece in your wardrobe.

The Maxi Avalon Smock Dress is your go-to for those “I have nothing to wear” days. With its oversized fit and sweeping maxi length, it’s the kind of dress that makes zero effort look like a full-blown outfit. Wear her with sandals for a school drop-off moment or chuck on some boots and earrings and call it a date night (even if it’s just to the grocery store without the kids).

We’re talking billowed sleeves for the drama, functional buttons and pockets for the practicality. And yes — she’s made from 100% cotton, so it’s all breathable, all day.

Why you’ll love her:

  • Oversized fit
  • Flowing full length for that effortless, elevated vibe
  • Billowy sleeves that move with you
  • Functional buttons and actual pockets (the holy grail)
  • Made from 100% breathable cotton
  • Colour: Jett Black
  • Bump-friendly, breastfeeding-friendly, brunch-friendly — you get the idea

Please note: Customers often choose to size down in this style for a less oversized look. Please double check the size guide before making your purchase or reach out to our team for sizing advice. Colours can appear lighter on screen.

How It Fits (Spoiler: Like a Dream)

This style is intentionally oversized for that flowy, relaxed vibe. If you prefer a closer fit (or you’re on the shorter side), size down. Taller babes? Stick to your usual size to keep the length. Check the size guide or reach out to us if you’re unsure—we’ll help you find your perfect fit.

A little TLC for your piece

Customers praised this versatile smock dress as "comfortable and stylish," perfect for all seasons. The high-quality fabric is lightweight and breastfeeding-friendly. However, sizing runs very oversized—many recommend sizing down 1-2 sizes. One concern: the thin material can be see-through in direct sunlight without lining.

Maxi Avalon pink gingham 💗

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! 💗

Stunning 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.

The most beautiful maxi dress I own!

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.

My favorite dress ever

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!!!
