DIY: 90’s Halter Crop Top (From a Tank Top)

DIY halter crop top sewing

I first came across this top on the Forever 21 website and fell in love. It’s so simple yet so basic and versatile that I think it can almost pass as an essential. What I love the most is the halter neckline, and who doesn’t love a 90’s vibe? I’ve been seeing this top everywhere lately. Other brands sell their own versions of it too.

You can definitely make this top from scratch, but if you’d rather make it out of an old tank to skip the start-from-scratch process, then I made this post for you. It’s also a good way to give back life to an old boring tank that you perhaps don’t wear anymore. I hope the trend sticks around for a while since I just finished making my own! Haha.

Let me say that this project might take some time, but it’s totally worth it. Now that I’ve said what I wanted to say, let’s get into the tutorial!


  • Well fitted tank top/ camisole (doesn’t matter if it is single strapped or wider like mine. As long as it has border hemming that can serve as the strings to tie behind your neck—see step 1—you’re good)
  • Scissors
  • Chalk for marking
  • Measuring tape
  • Sewing materials: sewing machine/ needle, thread


I don't know how the white chalk mark vanished in the second part of the picture. Weird. The first two parts are the same thing, just showing before and after, so don't get confused!

① To create a neckline that is 5 to 6 inches wide: Find the centre of your neckline by folding the top lengthwise in half and marking with a chalk. Unfold then measure about 2.5 to 3 inches from the centre mark towards either side and mark.

You could hold up the neckline right under your neck to see if you’re happy with how wide your new neckline will be and adjust accordingly.

Now to create the two strings for tying: You will need to separate the hemming from the rest of the tank, except inside the 5 to 6 inch mark portion (see image above). To do this you should cut as close to the hem as possible. Do this slowly and be careful not to cut the hem itself.

Once the separating is done, snip the hem in half at the back to create your two strings. The length of your strings you get will depend on what type of top you’re using.

A low-necked or low-backed tank (like mine) would be perfect. This gives you more hemming and therefore longer string. And if you’re using a top that has a single strap, then it makes things easier for you since you would need to do less separating.

TWO. Wear your unfinished top and tie the strings behind making sure the neckline is high. Then on one side, fold the excess fabric inwards to get an angled folded line. Adjust till you’re happy with the angle and then pin into place.

Remove the top and fold lengthwise in half. Keeping the pinned side facing up, align both sides of the top. This is to get the exact angle on the other side as well. Trace out the angled border with your chalk; fold and pin the other side too in the same way.

Now you’ll need to cut off the excess fabric leaving about 1/2 an inch of seam allowance along the angled sides, and…

THREE. …while you’re at it, you could continue and cut a straight line across the back. So by continuing, you are creating seam allowance for the back as well. To hem all these borders, fold in twice and sew.

I’m sorry if the picture above is confusing. That’s because I cut and hemmed the angled edges and the back separately. You could do it whatever way works for you!


step 4-w-compressed

FOUR. We’re almost there! Wear your top and mark where you want the bottom to end. I let mine end a teeny bit above my belly button.

Remove the top and fold lengthwise in half (yet again) then draw a straight line 1/2 an inch (seam allowance) below the chalk mark created. Cut along the line and then hem.


step 5-w-compressed

FIVE. This step is only for those whose tops don’t hug the waist well. All you need to do is turn your top inside out, mark slanting lines, sew along them and cut off the excess.

And with that you have yourself a cute transformed crop top!


I hope this tutorial was easy to follow and understand. I feel like I complicated a few parts (eek!). But if in doubt, there’s always the comment section below.

Please don’t forget to tag me on your Instagram pictures if you do recreate this! I would love to see them. My Instagram icon is on the right sidebar.

All the best!
