Too much of a Good Thing?

So I bought the Star Runner Halfzip in Plum/inkwell Hyperstripe online, and I love love the color. I really wanted the Run Full Tilt pullover, but my store didn't have my size, and the 8 was too tight for comfort. I was all set to rip the tags off of the half zip when my store suddenly had a size 12 on markdown. I tried it on, and while the 10 would have been perfect, this is still a good fit. So now I have 2 shirts in the same fabric, with slightly different purposes. I love the pullover as a nice but technical shirt to wear with jeans, and te Halfzip for the beach, walks, and everyday craziness. The bust seam on this one has been criticized, but I think that it almost helps minimize my mega boobs. And I love the kangaroo pocket. 

Am I nuts??
