Although I refuse to spend copious amounts of money on such things as underwear and bras, there are some things that can be justified. UK label Bordelle is positively the most crafted and gorgeous lingerie out there, with hints of S&M and birthday-present-esque tailoring. Barbarella would be thrilled.
VPL (Visible Panty Lines) by Victoria Bartlett, encourages underwear as outerwear. Few people can really pull this off without looking tacky and unkempt, but paired with jersey layerings, a little sheer, and some futuristic cuts, you've got android chic. I'm a fan.
