My thoughts on Tiara:
1. She is so young! 7-8 in MOST of above videos, now 9yo and oozing femininity. Some girls from "starlets" are early bloomers physically, but not a single one of them had been such a sexual magnet psychologically as Tiara.
2. Her waist-hips ratio is absolute perfection and she accentuate it in her hypnotizing moves.
3. Besides her fine body, watch her face as well - she is swirling her tongue and biting her lips in most provocative ways and in best moments of her dances!
4. Many of her dances look free and improvised. Obviously she has been learning moves from social media, but she adds A LOT of her own to them and composes unique pieces of art. It's not labored at all.
5. I think because of point 1↑ her mom got spooked. I mean the 8-9yo girl owning her femininity to the point of rapidly gaining thousands of followers may have scared her off.
