If it's your first wet look piece: choose stretch vinyl over rigid patent. Stretch versions move with you. Rigid patent needs exact measurements.
If you'll wear it for hours: pick strappy styles over full coverage. More skin showing means less heat trapped.
If you want maximum shine on camera: wipe it down before you shoot. A soft cloth lifts the fingerprints and dust that dull the finish.
If you're between sizes: size up. Wet look has less give than lace, and too tight shows every seam.
Keep it away from heat. Hand wash, dry flat and never iron. Heat can crack or melt the coating.
