Who to talk to

I'm sorry to say that the answer is no one. These parties are optional and to be offered by someone, not deligated by you to someone.
Anyone whom wishes may offer- regardless of position. If no one offers, you do not have them.

A bridal party is your bridesmaids and maid of honor so I’m not sure what you’re asking? A bridal shower?

You shouldn’t tell anyone that you want them to throw you a party. That would be extremely rude. If they want to host one, they will offer.

What pp have said is somehow truth, however doesn’t mean you don’t have to have one. You can host this yourself and maybe once you are you’ll get a little help from your bridal party. You can also opt to have bridal shower and bachelorette party all at once.

You can plan for all the girls to meet up
with you as a bachelorette party of shorts, I would not ask someone to plan you a party.

I wouldn’t ask anyone to host a party for me and to be honest it’s not something that’s required or should be expected. Many people will tell you it’s rude to host a party for yourselves or yourself (engagement party, bridal shower, bachelorette, etc), but we hosted our own engagement party because we wanted to celebrate with friends and family and no one in our circles thought it was rude or strange at all. My MOH is already talking about bachelorette party ideas (450+ days till the wedding, she’s excited), but if you want to do something and your girls can’t or don’t have time to plan, I don’t see any reason you can’t invite whomever you want and plan something yourself. I see why people think it’s rude to host your own bridal shower since it’s traditionally a gift giving event, but it doesn’t have to be traditional. I think if the focus is on spending time together and having fun, there’s no reason you can’t plan a get together yourself, that may not be a popular opinion, but you know your crowd better than we do and they know you. Happy planning!

View Quoted Comment That's it, bridal shower. It's been a long day.

View Quoted Comment Thank you.

My maid of honor is my sister who lives on the other side of the country. I was bummed because I thought nobody was going to plan a bachelorette party for me (I just wanted to get together and have a fun weekend with the girls). I was thinking of just planning a girls weekend that was unrelated to the wedding and inviting the same people who would have been invited to the bachelorette. I mentioned some ideas that I had for a girls weekend to one of my bridesmaids and she immediately jumped into action and planned a bachelorette weekend because she realized my sister was not doing it. Honestly, it may be a case if nobody knowing who is going to take responsibility for it since your maid of honor traditionally would take the responsibility.

View Quoted Comment I agree.
Besides being 100% honest and saying you want a shower you can hint by way of asking. "Do I need to plan on buying an outfit for a potential shower?" "Do I need to take a day off work for a shower or anything?" Stuff like that. Totally passive aggressive I admit. Likely will get the job done. If all else fails tell your co-planner of your desire and ask her advice in confidence. You may not end up with having a shower or bach party but ya tried, right?

I honestly don't see why you can't plan your own in this situation.
Sure someone else traditionally does the planning but tradition is getting tossed out more frequently for a reason. Also if you plan it yourself you can have your daughter help and she'd probably like that.

This is tricky. Typically it isn't proper etiquette to ask for these parties, BUT I think it also depends a lot on your crowd. For example, no one offered to throw me a bridal shower, and I really wanted one, so I asked my mom if she would...she said yes. I felt comfortable and knew I could ask her, but I probably wouldn't of felt as comfortable asking my bridesmaids. Since your wedding is still over a year away, I'd wait until around 5-6 months out and see if anyone offers. If by that time, no one does, then maybe you can mention it to your friends or mother or family how you really would like to have one. See if anyone offers then. You know your crowd best, and these are supposed to be our nearest and dearest so we should be able to talk to them about things like this. It feels awkward, but more often than not they just don't think of it and probably wouldn't have an issue with throwing one (might even be happy to).
