The only exception to this I can see is an occasion wear EVERYONE is going to be dressed to the same level of expense, which is usually weddings or galas (where non-muslim co-workers might be in ballgowns). Still have to be sensible in regards to zeenah if non-maharam men are present of course.
But I still love them in regards to being with my Muslim family members and my sisters in Islam who I know well enough to know that they only wish me well for whatever I can afford (and what I can give them after I've worn it a few times lol---if only there were more sisters my size so i could trade more easily---Sarah is the only one!!!!! now that Megan is hopefully settled somewhere nice and warm!!!). I love the one below for wearing with my girls, the middle ones for special occasions, the top one for a wedding, and the second one from the top I might wear out.
