Hi there my name is Kendel and I’m here writing a guest blog to share how I created these Vacation Romper/ Cold Shoulder Jumper mash rompers!
It started with this Pin. 
I saved it in hopes of figuring out how to make it. When I made the Vacation Romper for my twins I realized it was the perfect top to match the Pin. I have used the Cold Shoulder Jumper for other Romper Mashes in the past like this Ocean Breeze/cold shoulder mash so I chose it to create the bottom. 
First things first you will need both patterns. You can get the Vacation Romper here (afflink) and the Cold Shoulder Romper here (afflink). I was able to accomplish this hack with my projector without printing. I will show you that if you are a projector user as well as paper version. 
Cutting
Projector
I pulled both patterns, in A0 format, up on Adobe in different windows. Neither of these patterns have been adapted to projector format yet so it will take just and extra step of confirming what size you are cutting as all will be displayed. Starting with the top of the Vacation Romper (VR) cut the neck slope and the armscye stopping at the point of the armscye.
Switch to the Cold Shoulder (CS) pattern. Aline the point of the armscye on VR to that of CS and cut the body of the CS so your top will look like this. 
Cut a total of 2.
Cut the waistband and pants of CS as directed. I chose to omit the cuffs on the pants and add elastic for a cropped look but if you would like to use cuffs you will cut them as directed. I used the cuff as a measurement for elastic for that option. Cut the neck and arm binding from VR as directed.
Paper
Print the front bodice, pants and waistband of the CS as well as the cuffs if you are using that option. Print the arm and neck binding of VR and you will only need the top part of the romper so check the page layout for your size to save paper.
Using a straight edge draw a line from the armscye point on the CS bodice to the fold edge. 
Cut this line. Draw a line from the fold edge to the armscye point on the VR.
Then layer the bottom part of the bodice of CS on top of the VR along the line. 
This will be you new bodice piece cut 2.
Cut the waistband and pants of CS as directed. I chose to omit the cuffs on the pants and add elastic for a cropped look but if you would like to use cuffs you will cut them as directed. I used the cuff as a measurement for elastic for that option. Cut the neck and arm binding from VR as directed.
Assembly
Sew the side seams of your bodice.
Attach the waistband and the pants as you would if you were constructing the CS romper. Add cuffs if you have chosen this option or if you are doing the hacked cropped look you will overlap the elastic by ¼ inch and secure with a stretch stitch. Attach the elastic to the wrong side of the leg opening using your favorite stretch stitch or serger. Turn the elastic under to the wrong side and top stitch with zigzag or coverstitch. 
Attach the neck and arm binding per VR instructions
I added decorative bows to the front waist and shoulders. To do this I cut a 1” by 30” strip of fabric and stitched the long edges right sides together with a 1/4” seam allowance. Using a safety pin (or favorite turning tool) turn tube. Cut 1 16” and 2 7” pieces. Stitch the center of the longer piece to the center front waist band back stitching a couple times. 
Do the same with the smaller pieces to the top of the shoulder strap.
You are done! Show it off! I can’t wait to see it!
