If you wait and be patient, can a goatee grow back when the designer stubble gets past the stubble phase?

Yes, a goatee can grow back if you wait and are patient. As the designer stubble grows past the stubble phase, it will eventually form a full goatee. It may take some time for the hair to grow to the desired length, but with patience, the goatee will eventually grow back.

No, designer stubble is created by trimming hairs to a specific length, and does not have the same growth pattern as a goatee. A goatee is a beard that is grown on the chin and the lower part of the cheeks.
