Front button brassiere: Yes, the image clearly shows a bra a front button closure with full coverage

* Non-elastic brassiere: This is a bit more nuanced. The bra does appear to have some give and flexibility, which likely means there’s some elastic component blended into the fabric for comfort and movement. However, it doesn’t have the traditional stretchy, high-elastic underband or straps that a typical sports bra or wireless bra might have. So, in the sense of being predominantly non-elastic, yes, this aligns with the request.

* Wide Straps: The straps are wide and appear to be designed for comfort and support without digging into the shoulders.
