What's the point of getting authentic vs. replica jerseys?

Authentic jerseys are more expensive, and to me, less practical. Why would you pay extra for them?

The Jerseys are Better Quality

The Stripes Decals are Stitched on

I think ALL of them come in GIANT sizes. Personally... I'd love an authentic one, scaled down - little - so I could dream of being tough. Dream as I might wearing my authentic autographed jersey, I don't look tough at all in it when it's longer than every dress I own. It is very well made though, stitched decals, just as Onknight said.
