Sandro Tropea Tiered Dress

50 shades of blue color this dainty Sandro dress will flow effortlessly and is very easy to style. the elastic at the bust of this dress is pretty stretched out, specifically in the armpit area. I bought this unaware of this, so selling below what I paid. It needs to be fixed somehow, perhaps safety pin or something similar?
