Jessica Alba inspired this DIY with a trompe l'oeil sequin "necktie" sweater. To create your own tee with a sequin tie (perfect under a blazer), you will need a gray T-shirt, scissors, black sequin ribbon, masking tape and fabric glue.
Use masking tape to mark the borders of where the sequins will go, an area roughly 1 1/4" wide straight down the front of the shirt. Lay the sequin ribbon between the tape borders, leaving an extra 1/2" in length on each end. Adhere each row of ribbon to the shirt with small dots of fabric glue (a little goes a long way). Press each row of ribbon to ensure full contact with the fabric and allow it to dry. Optional - add a few stitches to the ribbon for reinforcement.
