What crochet stitch is similar to a garter stitch in knitting? I was thinking about making a scarf at some point like the scarf from the 4th Doctor in the Doctor Who series. The original scarf was knitted, which I am not capable of. I like the appearance of the garter stitch that was used and is commonly used in knitting. Single crochet is a simple enough stitch but the appearance is very different.

I understand that an exact match is not possible, but the garter stitch has those nice horizontal thin rows without the "bulk" of the crochet stitches. I don't think I can just slip stitch this, but is there some stitch or stitches that I could use that would be closer to the image on the left?
Another option, that has the advantage of only using standard crochet hooks, would be to use Slip Stitch Crochet. From the description of the craft this sounds similar to what Ji Ugug's answer is referring to. 

While the basic SS (slip stitch) is just inserting your hook through a loop, YO (yarn over), then pull through the loop you started with - Slip Stitch crochet works by changing the loops you insert your hook through and/or how you are inserting your hook into those loops (front to back or vice versa).

By working rows of slip stitches in front loops you can get the "garter" stitch. By working in the back loops you can get a rib stitch. The ladder of course more resembles its knitting equivalent.
