Flared yoga pants

[Treviarpelli]

I’d like 100% cotton black, shortish flared
yoga pants or failing that very lightweight cotton ballon leg trousers for Pilates - any help for where to purchase these please?
previous internet searches have been fruitless

Sorry, editing erased my original post recommending Bam clothing, the tulip leg pants are lovely but wrong colours, and the yoga pants come in 3 variants in black but are bamboo not cotton (but a natural fibre)

White Stuff Dolce pants are great when they're in stock.

Look on Vinted for Manuka or MLife.

I have just sold some which were too big and bought a smaller size.

This brand is absolutely lovely. Sadly no longer made so Vinted is the best source.

I turned to the past as everywhere seems to only have horrid cropped ruched things now.

BAM

Primark has great flared
