Awesome!
This is partly why I have styling certs to my credentials...no one does it on any level and so many people are unhappy.
I did work in a chain store bridal shop fairly recently. Even ordering one...most came in 2 weeks from order to arrival, although they say 6-8 weeks or more (bridesmaids dresses take longer to arrive then wedding gowns, so go figure that out...and they are usually made better). And these are not necessarily cheap dresses.
Started in the alteration department, and this is technically where my pay came from, but spent time on the floor. (I was fired, for the record, from sales...although I did occasionally get pulled in for people throwing massive fits.) The thing is, it's sell, sell, sell then up sell, up sell, up sell and get those alterations charged! Needed or not. So having all that extra is not a surprise...considering that was another $200 or more on the petticoat and hoops. Plus you work on commission, in sales and alterations, so with the high sales goal to make that commission, there is a lot of stuff sold and pushed onto brides that they don't need.
Our store was big on bust pads at $40 a pop. Most brides needed actual bras for support...and in my own shop I'll put them in, but still recommend they get proper foundations (which no one wears! At all! Like..oh my god!)
So that's why she had stupid stuff added.
