What's going on only at Schiesser?

Order this also bustiers of Schiesser for many years.
Unfortunately I have to continuously detect a deterioration in the quality, fit and cut.
Times the sizes were completely changed in a year, once the material times the processing. Then one year everything was as usual.
Unfortunately, there was this model so far only in black and white and my joy was great that finally came a gray variant on the market. Delivery of Amazon as usual tiptop.
However, I can not recommend this gray bustier. Poor fit, ultra-thin material and also the interface is completely changed. At the same time I have this model, ordered from another supplier in black. The black bustiers are impeccable.
Were the black may still be old inventory and the gray completely new and different goods ...? Anyway. I no longer order now.
