We don't know the actual measurements but your proportions definitely make your shoulders seem narrow.
First thing is loose fat asap. For you fat definitely pools in the abdomen area and love handle area which is giving a pear shape effect. Do you have normal or fat thighs? If they are normal then that means even losing 5-7kg would make a big difference, hopefully it won't affect your arms.
With regard to weight training yes, train your upper body asap. Although there is no actual spot training, if you do crunches it will tighten up and ultimately you will end up with an upside-down V instead of the pear.
But to be honest I think CLL would seem very odd with your current proportions.
