The quality of this slip extender is nice, but the fit is very unusual.  As others have stated, it has a 'pencil' type fit rather than a flowy, flared fit.  I ordered a Large hoping to overcome that but it didn't help. Surprisingly, the waist was a little snug for a Large too...I wear a size 8 and don't typically need a Large so I was surprised the waist felt a little snug.  The overall slip is LONG which means the slip part shows at the hem of my dress before you see the beautiful lace at the bottom.  If this had a flared effect and was shorter, it would be very nice, but sadly, I have to return it. I put the fit as somewhat large bc of the length, but the waist was somewhat small!
