Undergarment Question

Are any of you wearing Spanx or any unattractive lingerie under your gown?? I wanted to have on some sexxxy lingerie but my gown calls for a not extremely sexy bra that crosses over my stomach! Will you change when you get to the hotel???

honestly I bought special lingerie for the night and never changed into it! wore it the first night of the HM instead. granted, all I wore under the gown was my Mrs. Lynch boyshorts, and when DH unlaced the corset on the dress he didn't want to wait for me to put on lingerie

I'm not wearing any fancy lingerie under the gown - however I plan on buying some sexy stuff for the hotel that night
