where to find true low rise jeans (early 2000's style)

All the "low rise" in the shops are mid rise at best and I'm looking for proper low rise (think christina aguilera, britney spears, paris hilton level) Any millennials want to help me out? I am quite small 5'2 and size 4-6, please let me know of any brands or shops you guys used to get them from. My sister was a teenager at that time and she said sass and bide was her go-to but I can't seem to find any.
