opinions on hollister pants sizing?

I absolutely love hollister and have been on a little of a spree, but everytime i buy i realize a size 2 may fit me perfect, then on a different pair even a size 000 won’t fit me fine. Ive also gotten xxs bottoms and had them fit but an xs fit well too what to doooo when i order 🥹💔 just want to know if anyone struggles with this too
