Think a garment can only keep its base size? Nay. Biba gives you the trick to shrink a garment that is too big.
Boil a pot of water. When the water is boiling, place the t-shirt in the pan off the heat. The longer you wait before placing the t-shirt, the less it will shrink. It is therefore up to us to modulate the intensity. We recommend waiting 5 minutes to shrink the garment by one size or half a size. Then, you have to let the t-shirt soak, and the longer you wait, the more the effect will be visible.
For jeans, it's the same principle. We will place it in the washing machine at 90°C and with a rapid cycle. As soon as the washing is finished, we hasten to place our jeans in our dryer to tighten the fibers as much as possible. We can obviously apply these two methods in a confused way for the two types of clothing, and with all cotton clothing in general.
With these two techniques, you will never float in your clothes again!
