my fiance and i have this thing

so like my fiancee moved in with me last month. weve been together for two years but only recently decided to live together. im a freelancer so dont go out much, and she works from the office. anyways we got into this kind of weird routine where when shes home i want her to wear certain things, like tight jeans or something that shows cleavage. its not a big deal really but there are some days where if she isnt dressed how i want, i get so annoyed. it makes no sense since shes always attractive in whatever she wears. one day last week we had this argument about it and i could tell she was hurt. im scared that if i ask her to dress a certain way all the time or even just when shes home, its controlling and she might leave me. but on the other hand when she does wear something like that for me, it gets me really excited and turned on. do you think this is normal? am i being unreasonable?
