I bought an old meta petti second hand and it is perfect. It looks poofier in the stock photos, but it is just perfect for low poof and old school, etc.
Plus, it is pretty and very lovely quality. I am probably just odd, but I prefer wearing nice and quality items, just makes me feel prettier and more put together, even if you cant see it.
I think in general, most brand pettis are fairly low poof and made for stacking, so looking for any brand petti would likely be similar.
