White T-Shirts

I am feeling slightly perturbed now because I have just finished doing the laundry, and it has confirmed my suspicion that three of my white t-shirts have gone missing. Two of them, simple crewnecks from Uniqlo, I've had for more than two years and they were starting to go slightly yellow under the armpits (ew, I know). The other one was probably around a year old, and was a v-neck with a pocket, that my Mum said she disliked because it made me look flat. They were my go-to summer shirts, and now for the life of me, I can't find them anywhere. This makes me feel a little like I'm going nuts, especially since I'm the only one that does the laundry and puts them away, and hence should've been able to keep track of them.

I guess I need to go buy more white t-shirts.
