While the 50mm will give you wonderful DOF, you are faced with several challenges for Glamour photography when using this lens. First, lack of compression and working distance from the model. Second, for outdoor shooting in bright light, it is often impossible to shoot at f1.8 without resorting to ND filters. But they do work well in the shade.
Where blurring out the background works best is for relatively simple backgrounds but it does not really solve the problem with "busy" backgrounds, since they just end up being out of focus "busy" backgrounds, whereas a simple background when blurred by good DOF if often unidentifiable, which is often desired in Glamour work.
When shooting outdoors Glamour I mostly use a 70-200 F2.8 zoom. The 2.8 will work in all but the brightness sunlight without NDs and I can shoot at between 100mm and 200mm for a good working distance from the model to give her a good comfort zone and also get that pleasant compression result that comes from the longer mm range.
