Can you see a connection?

This Thursday, before we were going to a party, I put some clothes on my bed that I was going to choose from and wear that night. I had dinner and when I came back to the bedroom I saw it, can you?

Am I only having blue, black and white clothes with stripes??!

Well those are my favourite colors together with purple.

(I ended up wearing the dress in the down left corner; black skirt that's attached to a bluestriped oversized top with gold buttons)
