Everything's better down where it's wetter, take it from meee.
I made this a while ago, so not everything is pictured, but hopefully you'll understand!

*You can also pull it up and wear it as a dress and add a beachy hair clip.

Most of the time is made up of gluing the sequins, everything else is very quick.

  • Step 1


    -Strapless Bra
    -2 colors of felt

    *braided sequin ribbon for straps

  • Step 2

    Begin by placing one color felt onto the cup of the bra to figure out how much you'll need

  • Step 3

    Using this knowledge, sketch the outline of a clam shell onto the card stock paper.

    *make sure to make it a little bit bigger, you don't want your tata's hanging out!

  • Step 4

    Cut out the stencil and, checking to see if the size is accurate first, apply it to the felt and draw around it.

  • Step 5

    If you're planning to reuse this bra again, loosely baste the bottom of the clam shell to the bra.

    Do NOT go up all the way to the top!

    *If you're adding straps baste them on now

    Now continue to baste on the clamshell.
