I hate shopping

Why is this shirt only available in extra-small? It's *orange and purple plaid*! I really want one. Alas, I am a Target extra-large, not an extra-small. If I had better sewing-fu I'd be tempted to buy one and try to turn it into a dress for Junie, if I thought I could take the shoulders in somehow. (But maybe that's a bad habit to start, trying to live vicariously through my kid?)
