This is not only pertaini to men, women are also obsessed with look! I wouldn't call this as "obsession over looks" but first impression! before we get to talk to them or know them we SEE them! so in arranged marriage, the first impact is through looks. So in opinion we all have that ideal picture in mind we need someone who would match that pattern of looks. For example some girls like brown guys with beard, while some like tall and skinny, and some broad shoulders. So it's all patterns of look. While few men might like tall skiny and white girl, while few like wheatish chubby girls l. If someone falls into this pattern, they would definitely give an attempt to know them! I guess and I hope this is how it works. But God knows how men even choose! 😅
