Hi I'm new here. Been browsing around this forum for a while now and these look like a great starter pair to get me into the denim game. Though I need help with sizing, everyone says to go TTS or up one on the skinnies and some say as much as up two. I have a true waist of 31-31.5" and I need to know how much smaller is the actual waist compared to the tag size. About .5"? 1"? Should I go with 31's or 32's? I'm about 5'10" and 130-140lb if that helps.
