I use to wear it when I was about 125 lbs and small bust I was a 34b I think back then it is 29 and a half inches in front from shoulder strap to the tail it is not that length all the way around and 20 inches in back and side with no tail this is an approx. and it may be shorter when you put it on and i don't have a measure tape for material so I used a regular tape measure. Sorry I hope this is helpful
