I live in tee shirts during the warmer months and am trying to get as much life out of them while I'm on my "no clothing purchase" year.
I only buy 100% cotton, because those are most comfortable for me. I have a few favorites that are stiff, but fine otherwise - no holes, stains, etc. For awhile I thought it was our water, since we had a well, but we moved to a condo with city water, and I noticed some my cotton knits still get stiff.
I tried fabric softener and tumble drying them on the delicate cycle, but no luck.
Maybe it's the quality of cotton. Any ideas on reviving them?
