Have a look at Etsy.com, really great handmade things, invites, decorations girls would love. I have noticed more decorative LOL items at Big W, check their party department.

Pinterest has lots of ideas!

Make the party a theme so maybe get them all to dress up

Pinterest have literally hundreds of decorating ideas and party games!

i think i’ve seen (or you can make) an LOL pinata!

I’m going to suggest googling for any ideas or suggestions. Hope it all works out.

I’ve never heard of a lol party :/ But would suggest googling for some ideas and inspiration. Maybe you can convert a few old time party favourites to fit your lol party
Good luck, hope it all goes brilliantly

Have a look on Pinterest! I always get my inspiration and party ideas off there.

Print off th lol doll faces and use them as photo props. Maybe look on Pinterest and see if there is any ideas on there. Look on eBay for decorations.

The only thing I can think about for now is a Barbie cake! You could give a look at this tutorial

Maybe a pinata you could make one and just put lol on it. You could do a variation of egg and spoon with a balance the doll if you have two dolls and get them to balance them on their heads.
