I didn't have high hopes for the comfort level, just got them because I have the matching sieve bra, but wow, my expectations have been exceeded. They are comfy and flattering!

I haven’t had much luck with thongs in the past, but this item is very good quality and I hardly notice it while wearing. It pairs beautifully with the sieve bra for a matching set.
