All the fabrics used here are of 44/ 45 inches width.

The seam allowance is ½-inch unless otherwise specified.


I suggest you read the entire pattern once before starting to get a general idea.


All seams are to be finished by zigzag or serger.


Fabric Requirements




Gather the supplies.




** In the table below, “L” stands for the length and “W” stands for the width of the fabric piece to be cut.



Cut the pattern template for the romper shorts at the end of this PDF. Take the fabric for the romper, fold it lengthwise to fit the width of the template and keep the template on the fold as shown above. Mark and cut to get one piece of your romper shorts. Repeat the steps to get one more piece.


Refer table-2 to get the measurements for the top part of the romper and cut the top pieces with the required dimensions. Mark the top and side edges to avoid messing up.


You will get your top pieces and shorts pieces like the above (note that in the picture, the shorts pieces are not kept opened).


Cut two neck-tie pieces, also referring to table-2 above.


Take the front and back top pieces, layer them lining up the edges and fold in half width wise. Cut the appropriate pattern template for the arm hole, from below  and  keep  it  at  the  top  left  hand  corner  as  shown above.


Mark and cut out the armhole. Discard the smaller piece.


You will get you front and back top pieces like the above.


Zigzag the top edge of both the front and back top pieces. This is where the neck is formed.


Let’s    finish  the  armholes (you can either use the   readymade  ones  or  make  your  own  bias  tape  by referring to the tutorial here.


Cut the single- folded bias tape into 10-inch pieces. Take one of the tape pieces, place it slightly curved and press using plenty of steam (this will make it easy to attach along the armhole curve).


Open one of the folds of the bias tape and align its edge along the edge of the armhole, on the right side of the fabric as shown above and pin.



Sew the bias tape on to the armhole along the edge, removing the pin as you go.   Turn the bias tape over to its right side and topstitch along the seam line of the tape and the armhole as shown in the picture.


Fold the bias tape completely over to the wrong side of the fabric and press. Sew along the folded edge of the tape to secure.


Repeat the same with the other armholes.


Now fold the upper edge of the front piece by 3/8-inch and press.  Repeat  by  another    1  &  ¼-inch  and  press  again. Repeat the same with the back piece.


Sew along the edge of the fold to form the casing for the neck tie (make sure to reinforce at the start and finish). Repeat the steps on the back piece.


Keep the back piece over the front piece, with the right sides together, aligning the edges and sew both the side seams shut as marked by the lines. Take care to reinforce at the start and finish.


Our top is almost done, let’s move on to the romper shorts.


Take the two fabric pieces for the romper shorts and layer them with the right sides together and aligning the edges. Sew along the two curved edges as marked by the red line above.


Open up and you will see them looking almost like a pair of shorts.


Now we need to attach the top of the romper to the shorts.


Fold the top of the romper lengthwise, aligning the side seams and make a mark at the centre of the lower edge(this has to align later with the center seam of the shorts).


Let’s attach the top to the shorts.


Keep the shorts on its wrong side and the top on its right side, with its upper edge facing the upper edge of the shorts and slide the top into the shorts. Make sure that the mark on the top and the center seam of the shorts fall in line.


Align the upper raw edge of the shorts with the lower edge of the top and pin all around.


Sew the top to the shorts, leaving a seam allowance of 5/8- inches. Zig zag to prevent fraying. *Note that here we make use of the seam allowance to make a casing for the waist elastic.


Pull out the top you will see that it has started looking like a romper already.


Fold the seam upwards. Carefully sew along the  top edge of the seam to make a casing for the elastic. Leave a 2-inch gap to insert it.


Take the elastic, referring to the table-2 above and insert it through the casing using a safety pin. Keep the ends of the elastic overlapping and sew it shut



Sew the opening in the casing shut.


Let’s do the lower hem of the shorts.


Fold the lower edge by ¼ -inch and press. Fold by another
½-inch and press again.


Sew down the hem. Repeat the steps on the other leg of the shorts.


Now we can insert the elastic through the hem of the shorts.


Take the required length of elastic, referring to the table-2 above and insert the elastic through the hem. Secure the ends by sewing back and forth a few times.


Sew the inseams shut as marked by the black lines above.


Let’s do the neck- tie.


1) Take one of the fabric pieces required for the ties. Fold the two longer edges towards the wrong side by 3/8-inch and press.
2)Fold it again in half lengthwise, with the wrong sides together and press.
3) Flip the tie over to the wrong side and sew a straight line, one inch from the end of the open edge to the opposite corner to make the ends of the tie slanting. Clip the corners with the help of your scissors.
4) Flip the tie over to the right side, poke the corners out with the help of a wooden dowel and sew it shut along the open edge. Your tie is ready, make the other tie in a similar manner.


Scrunch the neckline and secure the ties by a straight- line stitch on both sides to set. And, your romper is ready!
