It is good you caught yours very early and most likely you'll never see melanoma ever again.
For sun protection: upf clothing does not lose it's sun protective quality. It is sun protective in how the fabric is woven, there isn't something in the fabric that would wash out or anything like that. This site which sells nice upf clothing explains how that works: http://www.coolibar.com/custserv/custserv.jsp?pageName=upf-ratings There are other sites and companies that also have good upf clothes. Columbia makes great lightweight shirts that I always wear when I go hiking.
Regular clothing works fine too, tighter weave fabrics will protect better. Don't spend a lot of time during peak ours in direct sun, and wear sun screen when you will be doing outdoor activities. The best and safest sun screens are listed here: http://www.ewg.org/sunscreen/
I live in California, another sunny state and I wear sun screen, upf sun protective clothing, and hats when I am hiking or know I'm going to be outside most of the day. Regular days I just wear regular clothes and sometimes wear sun screen if I know I'll be outside for more than 15 minutes. I always have a stick of suncreen in my purse in case I need it.
Don't change your whole life based on the anxiety of a small chance of getting melanoma again. Live your life with respect of the sun, get yourself and your kids in the routine of covering up when spending time in the sun. But most importantly, LIVE. By being anxious about this so often, you're letting melanoma win, and you've already kicked it to the curb!
All the best,
