DIY OPEN BACK CROP TOP from old T-Shirt

If you have some old T-shirts lying around, don’t throw them away. You can easily turn them into something great!

In this guide, we’ll change those old T-shirts into fashionable crop tops. You’ll learn how to make three different, beautiful crop tops. These tops can be worn in many ways and for many occasions, so they’re a great addition to your clothes.

So, let’s get started!

 

WHAT YOU’LL NEED

  • T-shirt

  • Measuring tape

  • Tailor’s chalk

  • Scissors

  • Pins

  • Sewing machine

 
  1. ROUNDED OPEN BACK CROP TOP

For this rounded open back crop top, use a tight-fitting T-shirt.

Start by measuring the length you want to make your new top and mark it. 

Use a pair of scissors to cut straight across the T, making it the perfect length for your crop top. 

Measure 4 inches from the bottom of your top and fold the fabric.

Pin the fold in place and sew two seams to hold the fold securely and keep it neat. 

Turn the T right side out and mark the middle of the back. Draw a straight line down the middle. 

Once you have a line down the middle, measure 12 cm on each side and draw another two lines down. Make sure that all your lines are 24 cm long. 

Then draw a curve using your lines as a guide and cut to create the gorgeous open back for your new top. The open back definitely makes this piece a show-stopper! 

Turn the shirt inside out again for this next step. Measure around the gap you just cut and create a 2 cm fold all the way around. Hold the fold in place with pins and then sew it down. This will definitely give your open back a perfect finish!

To create the ties, use the extra T-shirt fabric and cut two strips with a 3 cm width. 

Then sew two ends of the fabric strips together to make one long tie. 

Fold two of the sides towards the middle and then fold the strip in half to make the tie. Make sure you pin the fold in place as you work your way along the long strip of fabric.

Once you have folded the whole piece, hop back on over to your sewing machine and sew the fold in place. 

Attach a safety pin to one end of the tie and thread it through the channel you created in the back earlier. The tie is a stunning detail that adds so much to this open back crop top!

This crop top is so easy to make. It’s definitely got a business in the front, party in the back look! 

 

2. WRAP OPEN BACK CROP TOP

For this second crop top style, once again cut a small-sized T to get the cropped look.

Turn the T-shirt over and draw a line down the middle of the back.

Measure 2 cm from the bottom of the centerline and mark on both sides. Then draw a line from your 2 cm marking to the top of the middle line. If you want a more open back, extend your second markings by more than 2 cm.

Next, cut along your markings to create this fun and flirty, open back top.

In this step, fold the edges of your new back inwards. Pin them in place and then sew along your pinned line. This step will definitely give your crop top a nice clean finish!

To give your crop top a little extra detail, mark 10 cm from each side and make a few small folds at the marking. Sew over the folds to give your new top the perfect fitted look. 

Once again with that extra fabric cut two strips, each with a 3 cm width. Connect the strips together to make one long piece! 

To give your crop top the glam-up it needs, attach the long strip of fabric to the bottom front of your top, making sure there are equal amounts of fabric hanging off of each side.

Now that you’ve sewed on your strip, fold it just like you did for the first crop top to create an amazing tie for this new top. 

Finally, don’t forget to add a button and buttonhole to the neck!

The tie and the open back definitely add a bit of flirtiness to this stunning crop top! 

 

3. BOW TIE OPEN BACK CROP TOP

For this third gorgeous crop top, I recommend using a medium-size T-shirt.

Start by marking a line at 40 cm in the front and then turn the T over and draw two diagonal lines from the neckline to the center bottom of the top. 

Then draw another two diagonal lines from the center of your shirt, meeting the center bottom.

Get out your scissors and cut along your markings including at the front. 

Now that you have cropped your top, cut out the neckline of the T-shirt.

To give your new top an amazing finish and to avoid any fraying, double fold all the cut edges inwards. Pin them and then hope on over to your sewing machine to sew the folds in place.

This crop top is so fun and cute. I just adore it!
