keep in mind, white will be easy to be different color shade between fabric.
limited fabric, only few fabric has the color, not suitable for all designs
not too white, not too dark, mostly fabric with this color
show little yellow color shade. easy be different color shade between fabric.
some fabric white color showed more blue, we called it green white here. so if a dress in white color, but mixed by different fabric, one white dress will be showed different color. that can't be avoid.
this dress long sleeves asked for elastic lining. body body inside is satin lining. but the sleeves white lining is green white. the body lining is white. so this white dress showed two color difference.
mostly lace fabric is ivory, has not white. so need wash ivory lace to be white. but usually white lace easy to be washed to green white. so if we must use this pattern lace, and dress in white, will can't avoid two different color in a white dress.
