I ended up buying two of those skirts, one pink and one green - but managed to get both off Vinted for much lower prices (the green one was reasonably worn but in good condition and was only £17, and the pink one was new with tags and maybe £50-ish).
They still sell the green one (Olive), but not the pink one anymore. And it looks like the price for the new ones has gone up. The new blue colour (Lapis) does look gorgeous.
Here's my take, if it's useful....
The pros: They look lovely. I get loads of compliments, they're flattering on me, they're quite special and different, and pretty easy to wear - because they're a bit over the top, they look great with just t-shirts / plain jumpers, plus boots and tights; they don't need tricky styling.
The cons: Probably because I've got the Hush skirt to compare them too, the fact is that they just don't compare at all. The Hush one is a bit longer (more maxi than midi), more 'fuller' (or more consistent, maybe) in its ruffles and how it flows, and more comfortable.
The problem with the Eleven Loves one is the waistband - it's not really elasticated (at least not like the Hush one), it's got a ribbon through it, like a drawstring. This brings a couple of issues
Because I've got hips, I have to be very careful as I put it on to make sure the ends of the ribbon don't draw back into the waistband and get lost. I would just knot the ribbon at each end, but once it's on I then want to pull the ribbon so the skirt sits on my waist, and tie a nice bow.
Also because of the ribbon, the skirt works so much better when it's too big for you. If I could go back in time (or if I end up seeing that new blue colour on Vinted for a good price), I'd go for the biggest size possible. Because the waist isn't really elasticated, the skirt feels and looks best when the waistband at its biggest (i.e. when 'stretched') is too big for you, and then you pull it in, allowing for both a big bow, and the ruffles to flow better and not seem too far apart.
(I hope I've explained that ok, but I can try again if it doesn't make sense!)
Upshot: I wouldn't buy the Iris skirt at full price. But I'd buy it off Vinted, and if it was a bigger size than I wear. And in the meantime, I'm taking SUCH good care of my Hush navy one, as I never want it to fall apart.
