Easiest wedding dress purchase ever!  One and done!!!  I went by my bust and natural waist measurements, and figured I could go a WEEEE bit smaller for a snug fit, and the dress fits perfectly for my casual wedding.  Now I just need to choose a date, LOL!  Note:  I'm 5'11", weigh 185, with a bust measurement of 40" and a waist measurement of 33.5".  I ordered the size 14 in white.  The dress is only long enough to accommodate a flat shoe at my height, but might need to be hemmed for shorter people.  Also, the straps were ALMOST too long to accommodate even my height, so shorter people might find that they need to shorten the straps... which would be easily accomplished by a seamstress, but perhaps not by the amateur home sewist.  There is some nice padding in the bust of the dress; if you are small in the bust area, you might still wish to wear a bra, but if you are more endowed, you may not need one at all.  I hope this is helpful info regarding fit.  As for how the dress looks, I found it to be very flattering and much nicer looking than a $45 dress would look!  Clearly it is not a $5000 designer dress, but for a casual wedding, it looks really lovely.  No loose threads, no ragged hems, and the skirt lining fabric is not clingy and is slightly stretchy.  You'll need to think through your undergarment choice; I could definitely see black undies through the skirt; but nude undergarments should blend in fine and not show through the fabric.  I hope this helps!
