I have a mini flamingo Constance with PHW as well, and I love this bag. I bought it because I had enough bigger everyday bags and wanted something versatile enough for evenings and special occasions. Mine is obviously too small for everyday wear, but I think a 24 would be appropriate.
In regards to color, I love flamingo, although I typically don't like pink bags. The color is not too bright, but more like a neutral pink IMO. Not muted and matronly though.
I think the Constance is one of my favorite bags H makes!
