Oops, fortunately, I spotted this quickly and so I’m doing a quick edit of this post as these are not free they’re dollarbies.
I will say that when I find something in SL which is not only free or cheap but has a unique style and quality it just makes my day and this skirt with its big hud of plain and highly patterned options is a KEEPER!
I think it is actually called the “Balloon skirt” and if you look closely you will see the bottom hem has an elasticated look to it.

The top is also a gift and I’m glad I decided to try it out as although it does come with a hud of slogans/picture worn on the front I spotted that you can remove the slogan which for me personally makes it more wearable.
There is also 2 hairs, I did try one with 3 hats inc but I couldn’t get it to fit my head and tbh I didn’t want to fiddle so I will leave them as a surprise for you.
Then check the Arata group notices as well because in there you will find free Maitreya bento nails.
As for fits, limited to I believe a Maitreya body. As it happens a really good fit for me so don’t let that put you off trying them out. Then use the TP to the discount floor as there are some Kawaii dress fatpacks for really good prices.
