If you want to set the selected value that is coming in Model. You need to do it like this:

@Html.DropDownListFor(m => oProfile.BodyTypeShoulderId, 
                           new SelectList(Model.BodyTypeShoulders, 
                                          "Id", 
                                          "Name",
                                          oProfile.BodyTypeShoulderId), 
                           new { @class = "form-control input-sm-select" })

The above code will set the dropdown selected value to whatever is in the current Model object BodyTypeShoulderId

The first argument of DropDownListFor tells that on form post drop down selected value will be mapped with the Model property which is set there (we are passing m => oProfile.BodyTypeShoulderId) but this not sets selected Value.

For setting selected value you have to pass SelectList fourth parameter using this overload of SelectList class which is object selectedValue
