As suggested, paying attention to the laterial delt head and trying to increase the width of the upper lat's is a very good idea. If the traps become over developed (thick & slopping), than the illusion of shoulder width can be reduced. That can apply to the front delts as well, to a lesser degree. Too much attention to BP's, inclines, etc and not enough to overhead pressing and side delt work, can lead to this. A lot of guy's will have overdeveloped front delts and pec's (BP) while their laterial head seems out of balance. It's all about the "X" frame in bb'ing. Any wide hip structure can be overcome with a little planning as to how to increase fuller and thicker side delts.
Might consider the Press behind neck, upright rows (medium grip), lateral raises, DB presses, etc.All favorable influence on shoulder width. Good Luck.
