"No Ties, No Jeans" notation on invitation

...Maybe it has been a long time, Sophia!  They have these nifty new "Forever stamps" that are good for first class mailing, well, forever so you don't have to worry about current prices. 

I asked about those last time I bought stamps.  The post office worker got very huffy with me saying they aren't really needed because they don't raise the prices that often.  Also, they didn't have any in stock.

I may be wrong about this but it's my understanding that they are no longer issuing first class stamps with a preprinted value. In other words, all first class staps are "forever" stamps now. So they can't be out of them anymore unless they're totally out of first class stamps.

All forever stamps I buy magically morph into stamps of the previous price when my back is turned. It's like all music in cars turning into Best of Queen after two weeks in Good Omens.

They do have preprinted stamps https://store.usps.com/store/browse/uspsProductDetailMultiSkuDropDown.jsp?categoryNavIds=catBuyStamps%3asubcatS_S_45cFirstClass&categoryNav=false&navAction=push&navCount=0&productId=S_789404&categoryId=subcatS_S_45cFirstClass

OK, like I said, I wasn't sure. But I will say that a lot (most?) of them are forever now. The only ones I've been able to purchase at my post office for the past few months are forever stamps.

Coming in late to  "No jeans, no ties" discussion, is it possible that the hosts would have preferred casual, attire, but didn't want to see jeans below the backside?  I realize that it was an adult party, but young people were invited with their parents.

Did you ever find out?
