They're everywhere, my heart included. Plaid prints have always been a remote area for me, mostly because I had hated my uniform from the primary school years... But since I've been playing with stripes for a while now, I'm slowly trying to level up and fit in the wardrobe plaids, other prints being soon-to-come as well.
If you're part of the same category of people as me, who find foggy, cold days calling for neutral colors you'll probably love how these patterns give you the impression that you put in a lot more effort for your look than you actually did. It also comes in handy for my lazy ass who can't bother too much to look pretty in the early hours of the day.
If you want to get on board with this madnes of plaids, down below I have linked some cool pieces that I found at Zaful, so you can treat yourself with some if you haven't already.
