Drop-Seat Jammies 18" Doll Clothes

18 reviews   |  

Everything old is new again! Drop-seat pajamas have been around for 100 years. Your great-grandparents may have referred to them as Dr. Denton's, Trap-Door Pajamas, or a Union Suit. Now they're a fashion statement! This specially designed version, by Forever 18 Inches, for 18" dolls features a working "Trap Door," ribbed leg and arm cuffs, a bomber-jacket style neck, and a button-covered front and back that close with snaps or Hook-and-Loop. Options for hemmed pant legs and a plain back without the Trap Door are also included in the PDF pattern for those who want a simpler project. Also, good news for those with older dolls: the pajamas have been cut generously, and will fit most larger dolls. ( They easily accommodate an 11" waist and 12-1/2" hips, but do check your doll's measurements to be sure.)

The directions have been written comprehensively with many explanatory details for those who are newer to sewing. An experienced seamstress will probably be able to construct the jammies just by reading the instructions highlighted in bold text. Happy sewing!

Recommended Fabrics:  Soft woven fabrics such as lightweight flannel, or stable medium-weight knits with minimal stretch. Ribbing is needed for the neck and arm cuffs, and a 6"x6" square of lightweight fabric is also needed for the Trap Door lining.

I love my Union Suit,

I’ve made it twice, and have loved both. Used red tee shirt knit and it turned out fabulous. I used a flower print flannel on the seat. What a hoot. The pattern was straight forward and gave good directions. I usually don’t look at a pattern when I make things. As most are confusing and not the way I would make them. But the placements were needed and I was able to follow quite easily. Thanks

Dropped Seat Jammies 18" Doll clothes pattern

I had my eye on this pattern but what sold me was the pattern hack for Gingerbread Jammies. They were so much fun and very easy to make!

Drop seat jammies

This is a great pattern. Very easy to follow and construct. Although, I did not construct the “drop seat” as I opted to make the jammies w/o that feature my gdaughter loved them and one of her dolls (Ruthie) wore them the entire Christmas holiday. I made them as the gingerbread design. I do plan to make some more from flannels leftover from the sleeping bags I had. made her dolls a year ago. Such fun. Also, this fit AG doll perfectly. Honestly, I was quite pleased with the fit. Overall, excellent pattern, would be great to have this pattern with feet.
