Udy is an underwear brand established in the 50s in Spain. Ricardo Miguel Udi, its founder, began creating creating and selling underwear in Navarre (see here for more info). Since then, the company has been based in Madrid, and the brand was renamed Udy Collection in the 90s. All their products are designed and manufactured in Spain!
My favorite: the Wonderman in blue (as you can see from these sunglasses, I’m really into blue at the moment). The contrasting white waistband and trim is almost a classic now! But it is nice.
They are made of cotton and elastane (really soft and comfy) and have a little pocket on the inside. If you’ve not seen one before: it boosts your assets, giving you a confident bulge! It’s a bit like a wonderbra for men :)
