Reformation Phoenix Crop Top in Sunny Day

Reposhing this top. i love it but i've gained weight and it just doesn't fit nicely anymore. fits TTS unless you have bigger bust. i've worn and washed but there are no obvious signs of wear. last 3 pics are mine, post-wearing, the rest are the actual top too but just from when i received it. material "unknown" but feels like cotton/linen.
