Hi Kari -
Thank you for the feedback. This tank top was intended to be lightweight and breathable / airy for comfort on bike rides. The larger armholes allow for airflow and movement. I throw mine on over a sportsbra for mountain bike rides and around town. Understandably, this might not be everyone's style and I apologize we missed the mark in portraying the fit well enough to get that across on the product page.
I see you are within your 30 day return window and we would be happy to exchange for something different as long as it is unworn / unwashed. We have a lot of other shirt and tank fits that are a more classic style. Let me know!
