Poly Silk Lightweight Summer Print Tank Top

When I bought this, it was advertised as silk, but when I received it, it felt more like a poly silk blend. Still lightweight, not as buttery soft as expected, more crisp feeling. The tags killed me, so I cut them out, and I can't remember the brand, but it is NOT AT ALL stretchy and fits best on 1x or 2x with average bust (I have 42DDD and it just doesn't cut it despite fitting everywhere else). Pretty pattern, ended up only wearing for 15 minutes due to the bust issue. 😕
