I think if you invite someone to an engagement party that they will feel expected to go to the wedding. So if you invite them to the party then invite them to the wedding or just don't invite them to either I would say.
Semiformal means a suit and tie for men and a cocktail dress for ladies.
I personally think it is okay. I got married 4 years ago when I was fifteen but idk what it wud be like now to do that. I think it would be okay because it isn't a big deal if you don't wear it but It could also be okay. I hope this was a help!
Yes, it is etiquette for a family member to have their wedding before another family member as long as it is not in the same month or day.
When you have your engagement ring you should just wear the engagement ring. The band is placed on your finger at the altar the day you get married.
The wedding is for the bride and groom if its okay with them than its okay
No
Depending on your religion, it would or wouldn't be. If they are okay with it, go ahead! :)
Yes, and the Bride's parents as well as the entire Wedding party[ with the possible exception of the flower girls and ring bearer if they are very young].
It's best for FORMAL weddings.
Yes, velvet is an excellent choice to wear at a wedding for the autumn and winter months.
A social for an engaged couple or already married couple? If it's an engaged couple (such as an engagement party), I'd bring something small, like a bottle of wine and a congratulations card. If it's an already married couple, I would bring a gift if I did not bring one to the wedding (it's okay to send gifts up to one year after the fact). But, if we're talking about just some kind of get together, I'd do a very small host/hostess gift (flowers, stationary, kitchen utensil, etc...)
No. wait yes because black goes good with anything! even at a 5pm wedding.
