@quercus tomatoes which seem huge as part of italian cuisine are a new world food and thus not older than ~1500. But the key is that italian food isn't really all tomatoes and the tomato more elevated what what already "italian".

Traditional European clothes have always existed - those companies simply drew on the existing culture to create their stuff. Dyes and weaving have existed for a long time; many times only the upper class had nice clothes - but all the peasants would see the local nobles on fest day.
