Name, the sort of equivalent of the pound shop here sells these garbage bags (for building rubble) which are apparently perfect for tracing patterns from a garment. Just the right ability to manipulate, very large, and transparent enough to see what you're doing, supposedly. They're rubbish for actual rubbish though 🤣 I've been meaning to get some, pin prick outline should work with that too.
However, having done a bit of further Googling, I think the pattern is actually really basic. It may be very nice cotton (Japanese, maybe? It's made in Italy, do the Italians do a super nice cotton, I must admit beyond pima and supima I don't know much about cotton) but beyond that it's quite simple.
Final nail in the coffin was this blurb:
Cristaseya is an eclectic lifestyle project biasing between fashion, art, decoration and more. Collaborations are nurtured and welcomed, not scientifically planned, and translate into a cross-pollination of knowledge and crafts. Tropidelico is the name given to the fruits of these encounters. Cristaseya Tropidelico playfully subverts notions of use and form. A trait of dry humor lands a twist of lightness: objects are impeccably crafted and eminently useful, yet the iconography is turned upside down, resulting in a glitch. Something slightly unfamiliar or an apparent lack of sense invite users to quiz and interact. The Cristaseya Tropidelico editions ensure that form follows function, making it clear that both are simply a playful state of mind.
In essence, it's just another 'art' project, otherwise known as more money than sense person who attended an art academy for a couple of days decides to make things and reinvents the wheel by pointing at wheel and saying let's make those for ££££. You have to be just as clueless to the mechanics of the rest of the world to buy into it, I think.
