I'm pretty sure I won't have a Valentine this year either, but I still wanted to create some outfits just in case you're having a little trouble deciding what to wear. And for my fellow single girls, here's a funny quote I saw on tumblr days ago: "Shit it's nearly Valentine's Day and I haven't gotten myself anything". So wear something nice and treat yourself on this day as well.
My key to making these outfits was, not making it that obvious it was a Valentine's Outfit. So not too girly and too romantic. Hope I could help you figure out what you want to wear! But in case you're not inspired enough, check out my outfits from last year's Valentine outfit ideas here.
