This lace and satin petticoats can either be worn beneath a gown or laced into one to change the gown's description.  The lace and satin petticoats are off-the-shelf and trapped for LACE, UNLACE, WEAR, and REMOVE.
The lace and satin petticoats may be altered as long as it remains some sort of underskirt or petticoat that would be acceptable as part of a gown alteration.  It is not intended to be lingerie or risque.  Keep in mind that the petticoats will not be visible in your inventory when you are wearing it alone.
