In the winter, I have some turtlenecks I like. The added security of the covered apple is nice. I also have a pea coat which is nice because it has a small waist, and the bottom flairs out like a skirt.
As said earlier, skirts with leggings and boots are awesome!
In the summer, I've found that short sleeves will actually make my arms look bigger in some cases, while a cami will keep the shoulders relatively femanized, which is a nice surprise. Try one out! Find your color! Fat or thin, they're nice with a pushup bra underneath.
