ISTO
ISTO. is a Lisbon menswear label founded in 2017 on price transparency, on-demand production and 100% Portuguese manufacturing. Cofounded by CEO Pedro Palha with Pedro Gaspar, it sells wardrobe staples — heavyweight T-shirts, oxford shirts, chinos, knitwear and outerwear in muted colours — and publishes cost breakdowns per garment. Its "factourism" programme takes customers inside supplier factories. In July 2025 it brought in investment firm Altaz Capital as a strategic partner to fund expansion beyond its four Portuguese stores and Berlin shop, with London planned.
