From a lais interview:

When I shop, I never try anything on. I'm like, 'I know this is gonna fit.' I'm not the person who really follows, 'oh my god, this trend.' I would be curious to try it on and if I like it, 'yes, let's do it,' but I have to feel good putting something on, for sure.
Adriana Lima is always like that. She's like, 'I like this, I'm gonna put it on.' Anyway, she just gave me that confidence to wear whatever you want, because you feel good in it and you don't need to please everybody.
