"Love this flowing bright dress. I wore it on mother's day with leggings and a long sleeve thermal to under it. I even got compliments from the chef. He said I looked beautiful. It certainly makes you feel beautiful. Love the split in the front, it is a little long on me especially in flat shoes, but I had no problems walking. Size is comfortable, maybe runs a little large. I normally take a 22/24."
"What a beautiful dress! I already had the Maddy in natives and so loved the print, so when I got the opportunity to buy this beauty I was stoked! The long sleeves add an extra bit of class to a lovely dress. So many comments on how fab it looked! Thanks KR and PP"
"I love this dress so much. So many compliments as I walked through the airport x"
"Another absolute stunner by Kasey Rainbow and Proud Poppy! I am so happy with this dress!"
"I couldn’t be happier with my Bonnie long sleeve dress, colours, fit, fabric all perfect, I can’t wait to wear it. LOVE this dress"
"I love this dress. The print seems more vibrant than the OG one, looks better in real life too. Flowy sleeves that I love, deciding if I need a little take in or not, small wrists. Might be ok. It's a better fit than some other long sleeves. The length is great, no hemming needed, yay! I'll just have to wait a bit to wear it because it's so hot in Melbourne right now. Love it!"
"The colours are perfect for everyday wear or that special outing."
"Love this dress. I have purchased to wear to a wedding so haven’t worn it yet. In other brands I buy a 22-24. Purchased this in a 20 after doing the online chat. Could have gone with an 18 but this allows for a little extra room."
"Beautiful dress, fits perfectly, lots of compliments incoming. But be aware, the red/ crimson is a hot pink. On the desert pea pattern. It really looks red in the photos and videos. I was a little bit disappointed. That aside, I love the dress."
"This is my first long sleeve Bonnie and I love it. The colours are so vibrant and pretty, the material is light and flowy. I was lucky enough to buy one on sale in my size. . . 💜"
