Maybe I'm really, really missing something. Or maybe I haven't gotten far enough through the checkout process that I've been presented with the option. But are inner envelopes going the way of the dodo? I'm mocked up invitations on Minted, WPD, and David's, and never once noticed an option for inner envelopes.
I'm considering skipping them, especially if they aren't a standard, inexpensive option with where we're ordering. Would this substantially downgrade the formality of the invitation in your opinion? What if the outer envelope had a fancy foil liner? I would still address the outer envelope with the specific names of those invited.
And on that note, let's play one of my favorite games: what kind of wedding would you expect based on this invitation? (The gold-looking areas are foil pressed, but the ink is flat.)
