Here's a quick and easy basic for you. I've made the Sewaholic Renfrew before and have always wanted many more in my closet. It is such a great staple to have in several colors to work with multiple looks. I'm a big fan of the arm and hem bands. Here's the link to my first Renfrew with more of a review included in the post. That one is still a go to top especially in the warmer weather.
And in case you're wondering, yes- I think those are deodorant marks under my boob. Something I didn't notice until looking at the pictures. Damn you black shirts!
