Meeting the parents

Hey! I’m extremely nervous to meet my new bf’s parents! We are from different cultures, hes korean and i’m american.... i know that both of our parents are okay with us being together however both my mom and his mom have an older view on things so ik that it may be harder to accept. my mom has been accepting it well, she’s met him a couple times and things have gone nicely. i will be meeting his mom this weekend. just a quick hello. i really want her to accept and like me. does anyone have any tips? i’m just saying hello but is there anything i could do or bring or is that weird? i don’t know, i’m freaking out. also what should i wear?!?! 😭😭😭
