Can I dec on cape cast on neck in same inc area?

Hi :>), Have a cape pattern that inc kfb, need to make neck smaller. Can I dec at the same areas where the kfb on each side of markers were at? I am working with Cascade fake fur yarn. Their would be 2 dec's side by side, is that allowable? The cape pattern is called, vaudeville Furliscious and has not worked out as true to form, having to do more work on it & using bigger kn needles then what the pattern calls for. It does not come out to the full length that the pattern says. I just made it longer but need to make the neck smaller.

Anther question, I saw a vintage cape that came below the elbows. At the neck is another capelet like that layed on top of the longer cape. Both sections had a lot of frill / ruffles on both pieces. Is their a name for this type of half circle cape? I have always thought of capes like that as carriage capes like a lady would wear when ridding in a carriage. We lost power as I tried to down load the free pattern. I have retraced my steps with out any luck. Would love to know what the cape is known as if you can find out for me. I don't know if it was knit or crochet, doesn't matter which ever it is. I would love to know the name of those type of capes & to make one. Looked as if it might of tied with ribbon in the front but not sure. All I got was a quick look at it. THANK YOU for any help you can provide.
