Whiy don't you use the Marie skirt form gurda patterns? It's free online (lots of links about) and extend it to meet the high waistband. then take a simple tee top and copy the shape, adding width for the pleats.then fasten the pleats at the shoulder with a few stitches.
the marie skirt has its pleats arrange differently, but you could just ignore that and use the basic shape.
Good luck! I love these styles, making my own version too
I used a simple flared-skirt dress i already had, detached the skirt form the waistband, inverted it, arrange the pleats, and sewed it back on. Instant tulip dress! And the jersey means you don't have to worry too much about the stretch around the knees.

This is lovely! What they've done is this:
Taken an ordinary tank style, then cut a triangle shape from the right shoulder, into the waist, and then out again to the hem. then they inserted a rectangle at an angle to make up the neckline and left side. This has made a very baggy tank.
Then, they've ironed the triangles/pleats into the rectangle, stitching them down to take up the slack.
I suspect they've made a similar triangluar side seam at the back to create one forward-angled pleat.
This could problably be easily reconned from an existing tank. Or, if you make from scratch, make it as above, then use a dummy (or friend) to mark off the bottom hem to get it even.

Good luck!

If I can posit an alternative, I think it's not gathered at all!
It's definitely a double circle skirt as everyone else says, but I think because of the way it falls, it's not actually gathered at the waistband, just cut so that it fits exactly.

Having said that, it may be easier to use small gathers to get an exact fit, rather than trying to get it exactly right without.

Good Luck! And it is really cute.

Hey lovely crafters, just looking for some advice on this beautiful skirt shape: What piece shapes do you think are used to make it? I'm looking for a second opinion. Thankfully, the stripes help you see how it's made!

Many thanks, all....

These are great! the remainder would make a very lovely beret-esque hat; it wouldn't need lots of adornment either.

Does anyone have any advice for me when making this dress? I designed it on a wing and a prayer and I've never used jersey before. I've written out the design as below; the back with be quite plain but I have size DD breasts  and an hourglass shape and I just wanted to know if you think the top will work cut reasonably straight, if I should make any adjustments?
Any advice appreciated! (click on the thumbnail to enlarge...)

** have modified the bust section to be more fitted over the DDs; with the seperate straps it will have less far to fall and the curve should mean it scoops in underneath to be more closely fitted. I'll add an extra flat section between the top of the skirt and the bottom of the cups so i'll be able to stitch the crossover pieces to it, leaving no gaps. I also thought that if I hem to upper line of the bust pieces with ribbon (once i've tried it on) it'll prevent it from stretching and sagging too low? This way I hope to not have to make the bust pieces double layered.

Any thoughts? x x

that's so awesome! duct tape the inside to prevent tearing and you could wear it to hand out flyers... i sense promotion calling.....!

that's such a brilliant transformation, it looks really stylish!

that's incredible! I hope that got great marks, it looks very professional (and deceptively simple, so well done!)
Excellent illustrations too, by the way 

It's beautiful! don't worry about your boobs, they're great.
