Whether you're the bride, the one planning the party or a guest, it's good to know the "rules" of those fun, friend-filled pre-wedding fetes known as bachelorette parties. If you need to know some bachelorette party basics, start here. If you're in search of more specific do's and don'ts, keep reading.

Party Do's

Do make sure that everyone who is invited to the bachelorette bash is invited to the wedding. But don't worry about inviting all the females on your wedding guest list to your girls' night out.

Do be sure your fiance's female relatives are invited, even if you're sure they won't attend. If you don't want them to feel obligated to attend, you or your fiance can tactfully let them know that declining won't hurt your feelings.

Do look for group rates -- for meals, entertainment, spa getaways and so on. Many establishments offer such discounts.

Do ask the bride for input regarding the guest list if you're unsure whom to invite.

Do share the bill with all the party guests -- except the bride. If you're the hostess, you're not expected to foot the bill!
