Obsidian Crystal Sports Bra

Obsidian — Black volcanic glass, liquid-dark with silver flow lines moving through it. Obsidian is the protector and the mirror, grounding, shadow work, facing what's underneath. The dark half of the whole, and the boldest piece here.

The sports bra — Scoop neck, racerback cut, built for low to mid intensity training. Moisture-wicking four-way stretch fabric, double-layered front with a wide elastic band under the bust so it actually holds you in rather than just looking the part. Flat seams and bias binding to cut down on rubbing, and rated UPF 50+ so it covers you outdoors. The crystal runs across the whole bra as one continuous print, so no two come out exactly alike. Couple of heads ups, it's cut best for an A to C cup, so size with that in mind. And the fabric doesn't love rough surfaces, dragging it against brick or velcro can pull at the fibres, so treat it a bit gentler than a cotton tee. The size guide's in inches and cm if you want to measure against something you already own.

Made to order, built in the open — This piece is printed and made just for you when you order it, nothing sits in a warehouse, nothing goes to waste. The design is printed all over the fabric, so every piece comes out slightly its own. Because it's made to order, we can't take change-of-mind returns, but anything faulty or misprinted is always put right. Full details in our returns policy. Spiritual Threads is in open alpha: a real, working shop being built one honest piece at a time. The crystal meanings here are drawn from tradition and offered for those who want them, never as medical or health claims. Wear it as a symbol if it speaks to you, or just because it looks good. Both are the right reason.
