Questions about butterflies around Sims head and lighten from their bodies

It is from the fashion line in parkside :sunglasses:
The special effects are determined by what trait it has for bonuses.

I have a shirt that has a dust cloud so I look like Pigpen from Peanuts, but it's supposed to have a romance boost. I suspect some of those animations are wonky.

I believe the effects are randoms as well as the trait boosts given. I have a suit outfit with a red glitter texture and a sparkle effect for love.

I've seen others with hearts as an effrct with love traits too so maybe instead of random effects there are sets for traits and effects (i.e. more than one effect can have the same trait boost.)
