This Hello Sweetie shirt is an adorable glow in the dark top that lets your significant other know just how much you love them.
This tee is based off of the sci-fi series Dr. Who, as the fictional character River Song would call the time traveler this when she would see him. During the day, the shirt just has a bunch of images on it that Dr. Who fans would be able to recognize. However when the lights are off, the words 'Hello Sweetie' appear in green glowing lights.
What's great about this shirt is that even if you're not a sci-fi fan, you can still give it as a present to your partner as the endearing term is not restricted solely to Dr. Who fans.
