I just discovered these after using other stuff for years (ugh). These absolutely work! What a relief not to feel self conscious about "showing through" anymore!!! These adhere with a little water or your body moisture, and they STAY on with or without a bra (and I'm a large size)! No slipping or poking through whatsoever. I'm so thrilled! I can't rate or recommend this product highly enough! I'm getting a second pair: one for going out, and one for casual just so I don't wear them out. These are absolutely wonderful! The comfort and peace of mind is well worth the price!!!
