A slip and a babydoll are both short, light pieces, but they fit differently. A slip skims the body from the shoulder; a babydoll sits under the bust and flares. The underband is what decides whether either feels comfortable.
Slip or babydoll
A slip is a full-length layer, usually bias-cut, and can be worn under a dress or on its own. A babydoll has a fitted underbust and a loose skirt. Choose the slip for a smooth line and the babydoll for a softer, more playful shape. See what is a babydoll.
Underbust support
On a babydoll, the underband should support without squeezing. If it digs in, size up; if it rides up, the band is too loose. The bust should sit inside the cup, not spill over the edge.
Length
A slip should be shorter than the dress hem if you are layering. A babydoll usually ends at the hip or upper thigh. Check the length against what you plan to wear underneath.
