I frequently buy matching shirts for my husband and I to wear. We love wearing matching T-shirts when we are traveling, and at the grocery store.
I bought matching animal hats for my Grandson and his girl, and for hubby and I I think they are adorable.
On two occasions, I have bought 14 matching shirts for the whole family to wear at our family reunion/February birthday celebration. We used to get together in February because 5 members have their birthdays in Feb (I just missed by two days), and the December birthday boys got a chance to have a real party too, instead of combined with Xmas.
