This is a well made costume or casual wear corset and not for serious waist training.  It is pretty, very lightweight but not much compression.  The steel bust looks like it would buckle under tight lacing so I returned it.  I am 5 8 and have a 30 inch waist.  I bought the size 24 which was perfect.  If I had the need for a great costume corset, this would most definitely be it.
