This guide walks you through building a complete fish costume from scratch. You will start by measuring and sewing a hooded fish head with a dorsal fin, then create a stiffened tail using interfacing. The process continues with cutting dozens of felt scales from a cardstock template and attaching them in overlapping rows across a turtleneck shirt. Finally, you will add decorative details like eyes, gills, and glitter to complete the look.

Directions
- Start by constructing the hood portion that forms the fish's head. Measure the wearer's shoulder-to-shoulder width, then continue the tape measure over the crown of the head to the opposite shoulder. Take that total measurement, split it in half, and add four inches to determine the required height. Next, measure the circumference of the head at its widest point, divide that figure by two, and use these two numbers as your dimensions.
- Using your chosen felt color, cut two rectangular pieces matching those dimensions. Shape the top of each rectangle into a tapered point to form the fish's snout. Cut out an opening for the wearer's face and shape a curved triangle to serve as a dorsal fin.
- Begin stitching at the back of the hood, working up over the pointed top and down toward the opening. Position the fin at the rear of the hood structure. Flip the hood right-side out to check the fit and make any needed alterations. Secure a hook-and-loop fastener to the underside of the chin area.
- Personalize the hood by gluing on the white and black felt pieces for eyes, sketching gill details with fabric markers, or sprinkling glitter over the surface.
- With the head complete, shift your focus to the body. Sketch a large scale design onto the cardstock and cut it out to create a template. Use this template to cut out dozens of scale shapes from your felt; the exact quantity depends on your scale size and the wearer's dimensions.
- Draw your desired tail shape onto the felt and cut out two identical pieces. Sandwich the interfacing between these two layers to add structure. Stitch the pieces together along the edges, then attach the finished tail to the interior back hem of the turtleneck shirt.
- Begin applying the felt scales at the bottom hem of the turtleneck, arranging them in horizontal rows. Once a row is complete, move upward a few inches and attach the next row, ensuring each scale overlaps the one below it. Continue this process until the entire front and back torso of the shirt is covered.
- Finish the costume by applying glue and glitter to add extra sparkle and detail to your creation.
