Primark coat (similar), Mango tee, ZARA trousers (similar), Stradivarius bag, Sacha shoes*

Whenever I just don't have a clue what to wear, but I know that I want to be comfortable, I usually grab towards a pair of trousers and a plain tee. I got these trousers from ZARA in the sale last year and I don't wear them enough because they're a bit too big at the waist. I absolutely love these trousers though as they have a white panel on the outer sides of the trousers which instantly brings back some kind of colour into the outfit! 

What is your go-to outfit when you don't know what to wear and when you want to be comfy?
