im 5'2 and petite and when i was purchasing my gst, i was also debating over the PST bk with gold hardware. i decided the GST over the PST because the shape of the PST just looked too tall (if that makes sense - less proportional.) and the GST looked much better on me than the PST. I love my GST but I have to say, I do like big bags..the PST didn't fit all of my things, lol. but if you're going to use it for going out/dinner, PST is probably better. Either way, I really don't think you can go wrong. Choose the one you are most comfortable with =)
