What's your hairline like?

Judging just from the picture, you could get a small partial that could sit behind your natural hairline and just fill in the thinning area.
You could keep the hair long and let it fall & blend with your natural hair to create quite a heavy fringe.

This would make life very easy for you, as getting a good hairline is the trickiest part of wearing hair.
As your hair continued to thin and the front recede, you could increase the size of the template and incorporate the front hairline, by which time you'll be quite expert at it.

You're very lucky with your curly hair as this will be easy to blend and where it meets your natural hair will be perfectly disguised.

You are a long way away from needing a full cap.
