I had RNY (I think there's one wound with the VSG that's a bit bigger - the one they pull your stomach through - but the rest are really small - like all of mine were). They were tiny, and I can't see them at all anymore.
amount of excess skin depends on a lot of factors - your age, how overweight you were, how LONG you were overweight - as well as others. Most of us have at least SOME (I lost over 200 lbs, so I had A LOT). However, you're likely the only one who will notice. I eventually had mine removed because it was driving me nuts, but my husband was the only person who ever knew it was there. You couldn't tell at all when I was wearing clothes. Here I am BEFORE I had it removed. Most of mine was on my abs (although I had it on my arms and boobs, too), but I just tucked the ab skin into my pants and then wore slightly oversized, long-ish tops to hide it. Ta da! No more loose skin...
honestly, most people worry A LOT about the loose skin when they're pre-op or early post-op (I did, too), but most of us who are out a ways wonder why we worried so much about it. It's kind of a minor thing in the grand scheme of things, and it's usually not noticeable to others. And if it really bothers YOU, there's always plastic surgery. I think most of us would take the loose skin any day of the week over being morbidly obese again. I know I would!
