2 year anniversary party??

You could really do it however you want! If you still want to big traditional reception, go for it! As long as money is not an issue I don't see a problem with this. It might be slightly more casual but everyone can still get dressed up to celebrate you guys! I think many people are doing post wedding celebrations because of COVID and I don't think it matters whether you do it within 1 year, 2 years, or 10 years. Everyone deserves a celebration! I'd probably mention that gifts aren't expected.

I think that is a fabulous idea!!

i recently told my husband that for an anniversary like 5 year or something, i'd love to do an anniversary party. honestly i don't see any bad reason to celebrate your love and relationship!

So, I agree that you can throw a party whenever you want. Plan it however you like and invite whomever you want. Parties are great! But I just want to caution you from placing too much stock in this feeling like "the wedding reception we never got to have!" because that is probably an unrealistic expectation. Like someone said above, local guests will probably come but not many would travel for an anniversary party, no matter how much they care about you.

So, plan your party the way you want it but make sure you keep your expectations of the actual outcome (other than fun party, yay!) low.
