From the details on your email, we did noticed that it seems that you're using lots of different high chlorine based pool chemicals. Although, we are not an expert on pool chemicals, we think that its best to get an expert opinion on the products that you're currently using in your pool maintenance from a pool supply store, who's definitely more familiar with the types of products that are needed for maintenance, importantly the amount that should be used as well as how many times it should be use on a given period of time. We think that the reason you're experiencing discoloration on your swimwears is because the fabrics are reacting to the high chlorine level on your pool. Most swimwears are made from color safe fabrics that will not normally bleach out in just a few wear, but only under extreme situations could this be possible. Possibly, if you can adjust these pool chemicals, it can definitely improve your swimwear conditions. Additionally, when choosing swimwear, go with light colors, remember the darker your swimwear the more susceptible it is for discolorations. Try out different brands and see which brands holds their color better, and stick with that brand. Hope this helps. Got Question? Ask Underwear Click, click Contact.
