The red lace is a limited edition colourway, now discontinued, but this bralette is still available in black mesh, black modal, and assorted limited edition prints and laces. It doesn't have any additional lining so the sheer fabric options are just that: sheer.
The cut is a fairly simple wireless soft cup triangle bra with darts in the cups. The band is the same material as the crossback straps and clasps with a simple swan hook. There are sliders to adjust the length on both the band and the shoulder straps, but I do wish the band adjusted even shorter.
The Jessica bralette is a gorgeous lazy day bralette, comfortable enough to sleep in, and the back looks great under open back tops. The shape it gives is pretty natural so if you're not into that or you need heavy duty support, you might not like this one. If you're small and perky and wear bras more for decoration than support, this one's for you.
I've never heard of extenders being bad for bras?? Try it with 2!
