I live in Australia so sadly Hollister and American Eagle are not prevalent here. We have them (I think there is one shop in Sydney) but not like in the US. The best jeans for whale tails here were "Sass and Bide" those jeans were some of the lowest around in the 2000s. Another Aussie brand was "Bardot" they were super low rise too.
Some of my other favourites are Frankie B, Miss 60, and old school LEI (on MeganQT back in the day).
My wife wears Sass and Bide now, I scour Ebay keeping her in supply, and have recently bought her some AE and Miss 60 jeans. They are all low and which is great for keeping her g-string hanging out.
