Any tips on making my suit last longer?

Yes, if Slazenger I fear it's a case of "you gets what you pays for".
There are factors worth considering however.
Is your regular pool water heavily chlorinated?
(it is amazing the varied degrees to which managements of sports establishments
add the chemicals in what they think is the "right" proportion).
Is the shower water running very hot when you come to wash them?
Are they simply rinsed with the water or do you add a detergent ?
