Beautiful practical comfortable underwear...as it should be!

Love my Sieve Triangle bra and panties! And Customer Service were very helpful when I had to return and go up a size. I'm a pretty standard size 36C but I found the band a bit too tight for all day comfort and ended up with their size 4 or XL. Now I can wear it all day :)
