salaam ladies

i have a question: how fancy should ones engagement outfit be? I went shopping yesterday for it and my eye caught this light green and beige shararah..kam on the bottom and on the shirt
and a light orni with light kam...but my mom thought it was too simple and too light, and the kapra wasnt good enough...even the owner of the shop suggessted brighter colors..so she picked out this shimmery all over deep purple and blue shararah with heavy kam on the border of the orni and heavy kam on the shirt collar .sleeves ..and on the bottom of the skirt. (hm maybe i should attach a pic)
anyway i thought thats too much ..its just an engagement afterall..and im basing this on some of the engagement pics ive seen
