Well, I would try to talk it back or at least take it to a tailor and see if can be fixed.
Otherwise, I know that I only use my tri suit for racing. I use other workout clothes when I'm training.
I paid too much money for my tri suit (bottoms/top), and I can't have it wear out too quick. I should be wearing it for a couple of years to come!
And... if you get a new suit... then you can look into a 2-piece suit... which means easy access for using the restroom!
