I made this dress for Phoenix from a knit rayon (with a touch of spandex) in a big cat-inspired neon print. The bodice is lined and underlined in black cotton lawn. The underlining was absolutely necessary to provide the structure needed in the bodice.
Many of the roses and leaves on the dress (made from a lavendar light jersey - perhaps bamboo) are hand-stitched directly to the bodice (the stitches on the backside are obscured by the lining). There is also a free-floating "vine" with its own flowers, wrapped around Phoenix's waist and able to be posed any which way.
