That way, you can start the ball rolling with the invitation, and if you need guests to bring things for the theme, this can be included in the invitation. For example, if you do a girly award show theme make little awards and try to find a red carpet. Or, tell all of your guests to come in their girliest fanciest clothes. Even if you only have one guest coming you can still have some fun following these steps.

Make sure you list anything they will have to bring, like sleeping bags, pillows, CDs, etc.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/49\/Have-a-Girly-Sleepover-Step-3.jpg\/v4-460px-Have-a-Girly-Sleepover-Step-3.jpg","bigUrl":"\/images\/thumb\/4\/49\/Have-a-Girly-Sleepover-Step-3.jpg\/aid303898-v4-728px-Have-a-Girly-Sleepover-Step-3.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}
