Eyebrows grow back, so why not pick a shape and go with it? If you hate it, you can change your look within a few weeks. Most brows require constant tweaking to keep them looking good. Skip the tweezing and you will have fresh options shortly.
Finally, once you find a shape that works for you, stick with it. It is relatively easy to maintain an eyebrow style once you know exactly what you want. You simply need to remove hair as it begins to grow back to keep your brows looking fresh.
