I was interested in the Fern because it's a very popular item in the non-wired section, and I also loved the colour and style (it was one that I wanted).
It's a good bra. My only critique is that if you get bloated, especially during your period, this bra might be uncomfortable; this was the case for me. It felt super tight on my underbust while I was bloated, so I'm thinking of buying an extender for days when I wear this during my cycle.
In addition to this, I also feel that the straps don't fully support heavy chest; it does dig a bit into my shoulders and I think this bra would be perfect if the straps were wider for the larger cup sizes.
These notes aside, it's still a great underwire bra - you do get full support. I was also worried I would get cone boobs as my breasts are narrow; fortunately, this wasn't the case for me. It was true to my cup size.
Overall, it's a good bra (especially if you are lighter chested).
My breasts are narrow and 36 HH Envy from Panache is my true fit. If you are my size-twin I would suggest not wearing this if you get bloated bad, or at least wearing it with an extender during your cycle.
