It takes a day or two, but once I hear back from customer service, they are terrific and accommodating. I purchased 5 bamboo tees (M) and 3 pima cotton tees (M). i've been refunded for the sky blue tee, and I'm about to return the ones I won't be keeping. I ultimately chose the pima cotton with trepidation about the length and other shrinkage. The length of the medium bamboo tee should be the gold standard. Unfortunately, I will be returning the bamboo tees because I like the overall feminine appearance of the pima cotton tees. But I dread washing them. I know they will shrink and lose the length I was seeking from Onno, which I need. Hopefully, Onno will reconsider the length of the pima cotton tee and make them the length of the bamboo tees due to the shrinkage in the cotton. Better yet, make the cotton tees from preshrunk material!! Otherwise, the tees have a very short shelf life for me and that's wasteful and costly. Please make the pima cotton tees from preshrunk cotton and make them longer.
