I have spent entirely too much time thinking about Mark Zuckerberg's outfit at his birthday party

• Mark Zuckerberg had a 40th birthday party, which looked like a great time.
• But I noticed he had a slight outfit change in his photos. I was determined to find out why.
• Yes, I am aware there are better things I could do with my life.

The Instagram photos from Mark Zuckerberg's 40th birthday party left me with many questions. Questions that I am prepared to investigate using my skills not just as a journalist but also as someone who has attended a lot of parties.
