I'll be honest - I've never personally been a stickler for washing clothes before wearing them, but if you're going to take pictures, make sure you at least throw them in the dryer for a few minutes to steam out the folds and any wrinkles and creases from packaging/shipping.
OR you can get a clothing steamer. These cost about $20 at Amazon. Mine was a little more expensive (you can check it out here) but seriously, this thing is LIFE. CHANGING. I always (always always) forget to take my clothes out of the dryer, so everything I own is always wrinkled, and I can heat this thing up in about 30 seconds and have perfectly wrinkle-free clothing within 2 minutes without lugging out my ironing board. Not sponsored, just something that changed my life, haha!
