Hey Gottago!, are you a man or a woman? Disregard my advice if you're male, I can only speak from the ladies' perspective
You can wear a wrap no matter the
location of your stoma, the issue is that if it's lower the wrap will be over your underwear and may add some undesirable bulk in your pants. Especially since yours is lower I might recommend trying the actual Ostomysecrets underwear -- mine is slightly high (and my torso is long) so the waistband was too low, but for you it will probably work very nicely.
Personally I wear high-waisted undies from American Apparel:
store.americanapparel.net/subCategory/index.jsp?subCatId=high-waist-lingerie. I like the first two on that page, the stretch lace and the cotton. For me personally I find them really comfortable and they conceal and support the pouch very nicely.
When I need even more extra support or if I can't wear high waisted underwear to cover the pouch (like when I'm running) I'll sometimes use a maternity belly band that I borrowed from a friend (like these:
www.motherhood.com/maternity/belly-bands.asp). If you get the proper size it should work out of the box, I lost so much weight from this dang disease that in order to get it snug enough I have to fold it in half. In any case, it does work nicely.
Hope that helps! And... if you're a dude I guess I'll just leave this here for posterity...
