This is the shirt I first started out with. Very big. I decided to cut the neckline lower so I snipped off about 2-3 inches of neckline. Also, in that way, I can wear the dress reversibly. As for the logo, I haven't really done any touch-ups to it yet but I was thinking of either making a heart shaped cut out or putting a lace overlay on it.
So, put the shirt on and mark out your waist line with a pencil. I also decided to snip off the sleeves because they were droopy. Take off your shirt and fold it in half. Then cut along your waistline as shown above. You should end up with two triangular bits of cloth. Do not over-cut because this will determine how tight or how loose the waist is. It is better for it to be too small than too big because you can always cut more off after you've tried it on.
To get the knotted twist, you can either use your excess cloth to cinch and tie the middle part or you can invert the bottom of the dress. To achieve this, what you do is that you reach in from the cut-out waist portion and grab the end of the dress. Do this diagonally, which means if I reach in from the top left (arrowhead), I will grab the bottom right of the dress. Do this and straighten it out. Now you have the bottom of the dress inside out. So, repeat this process by pulling diagonally in the same direction you did before to set the bottom of the dress with the insides in.
And you get your finished product! No sewing required! Unless you would like to hem your dress. I used a cotton shirt so the fraying shouldn't be that bad. Not sure if I would wear this out yet since I have so many other clothes to wear!
I'm going to try and do bleach pen diys next.
