Must wear very high heels if you are going to dance in this dress. I got a 4L and 6L never even tried on the 6. Need a great strapeless bra if you are not very well endowed. Also, be careful of bracelets that can snag this delicate fabric. A real stunner, people complimented me all night, it got embarrassing!! lol Gorgeous--Not bad for 60 yrs. old!!
