OK, let me give you a tip...? If you are planning to really walk her for exercise, not just to potty, you may want to protect her hind feet because from time to time her nails will touch the sidewalk if you lower her a bit too much with the scarf while walking. If they scrape the pavement enough times, eventually there will be some wear to the nails. You might have noticed it looks like my dog is wearing little socks in the illustration.
If your dog is like mine, boots will not stay on her little feet with slender ankles. So I recommend vet wrap. It is the colorful self adhesive stretch bandage you can buy at the vet for about $3 a roll. It's the same stuff they use to hold a cotton ball in place after a blood draw. Cut about 7" of vet wrap, wrap it LOOSELY around the foot without stretching it. Then fold the whole foot in your hand and squeeze. The vet wrap will gum onto itself and your dog will be wearing a little custom fitted sock. And you know you are not cutting off the circuation because you did not stretch it. In my experience you can reuse the piece of vet wrap once, then you have to cut a new piece. I did a video of applying vet wrap a few years ago. I don't think I have it uploaded but I can upload it to YouTube if you need to see what I mean.
