Answer ASAP!!

Wendy🌻 • Mommy to 4 sweet babies. 2 beautiful girls and 2 handsome boys. Baby #5 is a GIRL and due in June!!
I know this is the wrong group, but I don't know where to ask and I need help. I'm new to being matron of honor. 
(I'm sending out the Facebook invite tonight) So my sister is getting married in July, but because my grandma will be out of state from may until beginning of July, were wanting to throw the bridal shower (I'm the matron of honer) March 12th! 
It'll be a Facebook invite, but what should I say in the description? Like I know I'm inviting People  to a bridal shower, but idk what to say! Lol.
