This is a size 24 slip from David's Bridal. The David's Bridal name is A-Line Medium Fullness 2 Tier A-line Slip Style 603.
I only wore this slip to try on dresses, so it was only on for about 3 hours total. I bought the slip when planning my wedding thinking I wanted to try on dresses with the exact slip I would be wearing. Then we eloped to Vegas, so I never really used it and don't need it anymore. I didn't use the slip other than to try on dresses. I have had it dry cleaned and the dry cleaner tags are attached. It is in perfect condition. It sells at David's for around $50.
