Wedding reception?

Allowing anyone to bring in their own alcohol usually means that the bride and groom can provide their own - for the reception. This is a great option because purchasing it on your own is much less expensive than purchasing through a caterer. While this is true, asking your guests to bring their own or telling them it is okay for them to bring what they want is a little out in left field. You should provide what you want and make concessions for your parents and your fiance's parents. Other than that, your guests will be fine with what you provide. Telling them it is okay to bring something they want makes it seem like you won't have enough.
