It's been so darn hot here that I'm wanting a sleeveless jersey. I'm about a size 4 everywhere except my bust, which demands a bit more room. I also have narrow shoulders. As a result, sleeveless jerseys gape horribly at the armholes, while being almost too big across the shoulders. It is not a flattering look!

Any suggestions for sleeveless jerseys that are cut wider through the chest, but still come in smaller sizes?
