So for Valentine's day my girlfriend got me a Hollister shirt and hoodie which was so sweet!

Over spring break I brought the shirt on vacation because it's a good-looking shirt and I look good in it. When I get home, I don't see the shirt and when I go looking for it, I can't find it. I realized that I left it at the place we we're staying 3 hours away.

I told my girlfriend I can't find the shirt but I said I assume it will turn up somewhere but in reality I just ordered the same shirt and didn't tell her that I actually lost it. AITA for lying and saying that I can't find it at home when in reality I know that I've actually lost it and bought the exact same one?

TL,DR: Lost a shirt, told girlfriend that I can't find it but I'll find it eventually, actually just bought the same shirt. AITA?
