Bridal shower and bachelorette????

You can do anything all none one etc!! a bridal shower is for gifts and you normally have a registry and then you have people over and have food, drinks, decor, cake etc, you play little games with people and you give them favors. and a bach is a party with you and your close friends/family like a spa day or a trip to mexico lol! i skipped the bridal shower as we already live together and i dont need more house crap and i figured by the time i purchased favors, decor, rent a venue, get a cake, food and drinks it would cost wayyyy too much!

You don't have to do both. One is fine to celebrate with your FH for the Jane and Doe since the cost will come to the same for the Bridal shower. If you feel that combining both events will save the cost for one day, it will be easier for your family and friends to come out and enjoy themselves along with you two.

The bachelorette is something you want to do with the girls for a weekend getaway.

I will also agree that everything was pretty well covered. The last thing I will add is that your bachelorette party can include family such as cousins if you are close with them. I'll put it this way because I don't know what's allowed and what's not. My one married friend told me if you aren't comfortable drinking out of straws that look like male genitalia in front of them, then don't invite them because anything can happen since the bride is usually not involved in the planning.

Seeing as how the others have this covered pretty thouroughly (Bridal Shower = women only + gifts + tea/sandwhiches in the afternoon, and bachelorette = bride's last "hurrah" as "single"), is there any other questions that now come to mind about it?

Bridal shower: Typically the women in your life (only those invited to the wedding, though) get together for some food and to "shower" you with gifts. You wouldn't plan this for yourself- someone throws you one
Jane/Doe, Stag/Doe, Buck/Doe: This is a wedding fundraiser. Usually held at community centers. People purchase tickets and then play games there for money. Usually alcohol is involved. More common in some areas than not. It's common in my area but I personally think it's tacky. I'm also in a US wedding wire forum and it's super uncommon there.

Bachelor/Bachelorette party: Someone in your bridal party typically plans this for you. Usually they are separate however a joint one could be fun. Usually it's a time to get together with your girlfriends and (usually alcohol is involved) and have one "last hurrah".

Bridal showers are more traditionally a ladies day of snacks and gifts, while bachelorette parties tend to be the last hoorah of drinking and (potentially raunchy) shenanigans before the wedding.
You can definitely do both.
You usually have a bridal shower to gather the things you need to set up a house, like linens and small kitchen gadgets so if you're already set or have been living together a while you might not feel like you need to have one which is totally ok. Some people do both, some people have either or neither. It's totally up to you.

I personally would choose one or the other- jack and Jill or bridal shower. Not both. To me they bothe represent almost the same thing but in different ways - jack and Jill is usually a way to raise money whereas a bridal shower is (usually only invite close female relatives) and they kinda bring you gifts. .. the wedding itself is normally cash that people bring but can do gifts as well if they so choose
The bachelor bachelorette party is usually for each gender to go out with their bridal party/close friends to let off steam before wedding as someone mentioned

A Stag and Doe or Jack and Jill are typically a small town thing where everyone knows everyone, so it's more of a community type vibe where everyone pays for a ticket to attend and that money goes towards the couple's wedding so they don't start out their lives together with a wedding to pay off. During the party games are played where guests can win prizes.

Bachelor/Bachelorette is a party with the wedding party and close friends of the bride and groom. Some make it a weekend getaway type thing and can be anything, from wine tours like Rayanne said, or a full out party weekend in Vegas. Depends on everyones budgets and what the bride/groom want.

Bridal shower is to literally shower the bride with gifts. I never understood the need for one since people bring gifts to the wedding any how, so whoever is invited to the bridal shower has to pay for 2 separate gifts, 1 for the shower and 1 for the actual wedding. That's what my grandma told me the first time I went to a bridal shower anyway, don't know if that's what's expected today but I think that's a bit much. And again like Rayanne, my FH and I have lived together for years already so we don't need many things so we're not even having a registry.

None of these parties have to be done if you're not interested in doing any, so just do what you're comfortable with.

A shower would be a time for any of your (female friends traditionally) to have a party to help the future couple get ready to set up their new home. Typically you would get household items. A bachelor/bachelorette party is usually a time for the guys or girls to blow off steam before the wedding. Usually just a fun night with your closest friends. You don't have to have any of the extra parties if you don't want to. Personally I'm not going to do the bridal shower. We have lived together for years and have everything we need. Some couples who live together will have a shower anyway as a way to upgrade some household stuff. I'm probably going to do a wine tour at the end of this summer as a bachelorette party. Mostly just because I love doing wine tours and I figure if I state that it's my bachelorette party more people will make the time for it.
