Vox one shoulder black dress

Like new condition Vox is a boutique in NYC. Size is XS I am not sure if there is a light colored marking on the front of the dress that can be removed with dry cleaning or if it is part of the material and reflection of lighting. You can only notice it if you are looking for it (see last picture) *Everyone has different opinions of condition please view all photos and ask questions if needed. Has been in storage in smoke free home
