2nd pg - when did you start showing?

This is my 2nd pg - I've heard from everyone that you start showing sooner with the second one.  For those of you who already have 2 or are on your second now - when did you start showing?

 I'm just wondering when my clothes will start to be snug - I really want to go shopping this weekend but I know it's not really worth it (well, maybe tops/sweaters would still be ok for a few months).
