top band:http://home.uchicago.edu/~evelynp/craftpics/HPIM0409.JPG
use a tape measure to measure around your chest just under your armpits (where you want the shirt to sit). make sure the tape measure isn't too tight because a too-tight strapless shirt give even the skinniest person armpit fat. take that measurement and add 1" for seam allowance. then cut a strip of non-stetchy fabric that is your chest measurement plus the 1" and is 5" wide. fold it over and sew the short side seams (1/2" seam allowance on each side) so you have a strip of fabric that now has a fold on one long side, a seam on each short side, and is open on the other long side. turn it right side out and press flat. there's your top band, set it aside.

bottom band:http://home.uchicago.edu/~evelynp/craftpics/HPIM0410.JPG
measure around your hips where you want the shirt to stop. you should actually measure around your hips while you have pants/a skirt on because the shirt band is going to have to fit over that. take that measurement and add 1". do the same as you did with the top band.

middle:
this part should be made of a kind of stetchy fabric. just using an old t-shirt would work (and would eliminate any need for sewing in this step). measure the length of your torso from where you want the shirt to start and to stop including the top and bottom band then add 1". that will be the length of your middle piece. then measure around the widest part of your chest and add 1". that's the width of your middle piece. cut that out fold over with right sides together, and sew up the other side (1/2 seam allowance).

assembly:
you have two long strips and one tube for this, so you're going to have to do pinning all the way around the middle section instead of being able the lay it flat, but it's not a huge pain. turn your middle part inside-out. take the top band and line up the open side with one of the open cut edges of the middle part and pin them together. the top band is going to be a little bit shorter than the middle section so line up one edge of the top strip and pin it right next to the seam on your middle section. then fold the band in half and pin the middle of the band to the other side of the middle section. then pin the other end of the top strip to the seam on the middle section. make sure that the two ends of the top band don't overlap. you need to leave just the TINIEST bit of space between them (like, a millimeter) so you can pull the two ends apart just a little bit once it's sewn to the middle section. as you pin keep finding the middle point on the band betweeen two pins and pinning it to the middle part of the main section of the shirt between the two pins so that you space out the slight gathering across the whole shirt (the gathering won't end up being too much in any one spot when you're done). once you've pinned the whole thing sew all the way around (1/2" seam allowance). make sure you don't stitch the two ends of the band together so they can still be pulled apart a little.

repeat for the bottom band.

now the shirt's almost done. you just have to hand-sew hooks and eyes to each of the bands. i put one hook and eye on the corner away from the main section and one right next to the main section (see the pictures) and it did the trick. then, viola! you've got a cute little shirt.

Je comprends à moitié lol
