This is an amazing summer dress! so pretty it stood out even though only a few were left on the rack. it's light, airy and perfect even for the hottest summer days. the straps are not adjustable but for me the dress was not too low and it fit just like on the model pictured. a very thin belt comes with it but adds nothing ,only detracts. i am usually a s or m in retailer sizing and the s was perfect. 
 ( for ref. 5'7', 140 lbs) this dress is so flawless and beautiful and i feel wonderful wearing
