Need help finding all-white gown!

Can anyone recommend some manufacturers that still make all-white wedding gowns? My daughter wants an all-white gown for her wedding next year but we can't seem to find them anywhere. Not a plain white gown - one that is embellished with beading & crystals.

Her style is pretty traditional - a strapless a-line gown with a dropped or basque waist & a train. She wants a motif on the bottom of the gown, though, and that seems to be causing a lot of the problem. I can find embellished white gowns but they don't have the motif at the bottom of the skirt.

Any suggestions on which lines to look at would be most appreciated!!!
