I like that look as well. Nothing like jeans for showing off a girl's beautiful shape. And as I am into upper body tickling mostly, a thin top is just the right thing. Better even than bare skin, in my opinion. I've never had the chance to tie anyone down though. My tickle partners so far have always been vanillas and don't want to be tied.
Its ok for viewing, but in my opinion it gives less access to the leg area
