Beautiful fit
Wardrobe staple! Easy to throw on, looks put together and so comfy
The comfiest dress! Need one in every colour!
This is my first Avalon Maxi purchase and I already have another on the way. The colours are beautiful together, the fabric itself is light and breathable and has a gorgeous drape to it. I immediately feel put together and comfortable when I pop it on - which is important because having 3 kids means time is not on my side when it comes to getting ready. I breastfed in it so easily too.
Stunning dress. The embroidery is so gorgeous, and it’s so fun to wear!
