I pretty much live in t-shirts and Polos with three buttons and a collar. These items don’t really require ironing. If you have to dress up, you need a shirt with a collar that buttons all the way up. That doesn’t mean it has to be all serious and and monochromatic though. If your dad has to wear button-ups to work, this I am Vader Short Sleeve Button-up shirt is just the ticket.
It has buttons and a collar so it’s dressy and stuff. It also has print that makes it look like Darth Vader’s armor, making it all geeky and cool. You can get the shirt all the way up to 3x size so there should be a size to fit your pops.
The shirt is available on ThinkGeek right now for $59.99(USD). You might get it in time for Father’s Day if you order right now; it’s perfect for the empire’s best dad.
