I just bought a sweater dress from Esprit.com http://www.espritshop.com/ called the attractive dress with stylish zig zag pattern (ha!)

I have wanted a zigzag pattern dress forever but now I am doubting myself...is it too young-ish for a 45 yo gal like me?

It arrived yesterday and it is seriously too hot to try on so no pic of me modeling it. I did for a mere moment to check fit and...it fits! Nice fit on the top, cute 3/4 sleeves and it hits about an inch above my knees. The fabric is really nice. Its very low in the front so requires some sort of layer.

It is clearly too warm to wear the dress NOW but when it cools down, I am thinking leggings and ballet flats. When full fall weather hits, black knee boots and maybe layer a long-sleeve tee under it? After this, I am stumped...how else can I style it? I'm very casual so I'm looking for casual ideas.
