A DIY gardener costume is the easiest adult costume there is: overalls, a neutral top, a sun hat, and a trowel in the pocket. Build the kids around it as flowers and garden gnomes and you have a whole garden family theme for about $10 to $20 a person, with no sewing anywhere in it.
Every year we go all-in on a DIY family costume, and this time our big crew did a colorful garden theme. As we add more kids, choosing a costume gets more interesting in the best way. Everything here is DIY, budget friendly, and easy to pull together at the last minute. Think colorful, comfy, and kid-proof.
How do you make a gardener costume?
Start with overalls and a neutral long sleeve top, both of which most people already own. Add a wide brim sun hat, garden gloves tucked in a pocket, and a small trowel or a pair of pruners to carry. Smudge a little brown eyeshadow on the knees and hands. That is the whole costume, and it reads instantly the moment you are holding a plant.

Garden Gnome Costumes for the Boys (DIY)
The boys made the cutest little garden gnomes. I whipped up the hats and beards quickly with simple materials like craft foam and faux fur, then dressed them in matching brown overalls and long-sleeve tees. This DIY costume was fast, comfy, and perfect for toddlers and babies, but could easily be upscaled to any size. Just saying, a whole family costume of DIY garden gnomes would be adorable!
Perfect for family Halloween costume ideas or themed class parties. For the full step-by-step on the hat and beard, see Garden Gnome Costume for Kids (Easy No-Sew DIY).
Giant Flower Costumes for the Girls (No-Sew)
We started with a big pack of multi-colored cardstock, then let the girls’ imaginations take over when it came to the flower headpieces. They loved helping with every step of these DIY costumes. They chose the colors, designed the petal layers, helped cut everything, and assembled their blooms. We added a basic green outfit for the “stems” and finished with a DIY flower pot skirt.

Dad’s Fertilizer Shirt (DIY “Plant Food” Costume)
My husband Stuart’s costume might be the easiest one to wear out of the whole family’s DIY costumes, because it is literally just a basic black t-shirt. I made the “bag of fertilizer” design with craft foam and my trusty hot glue gun. No Cricut or fancy cutter needed. Bonus idea: his fertilizer shirt with my gardener outfit makes a cute couples costume on its own.

How to Make a DIY Gardener Costume
My gardener costume is the kind I love because it’s all put together with items you probably already have in your closet. Cute overalls, a neutral shirt, a sun hat, and a small hand trowel were all it took. Simple, comfy, and it ties the whole garden theme together.
A gardener costume is the one adult outfit in this whole theme that needs nothing bought. Overalls, a neutral long sleeve top underneath, and a wide brim sun hat is the entire silhouette, and all three are usually already in a closet somewhere.
What sells it is what you carry, not what you wear. Garden gloves half tucked into a back pocket, a small trowel or a pair of pruners in hand, and a potted plant on your hip. Add a little brown eyeshadow rubbed into the knees and the backs of your hands, because a gardener who has not touched dirt does not read as a gardener.
If you want a gardener Halloween costume that works on its own rather than as part of a group, skip the overalls and go with a canvas apron over jeans, with seed packets poking out of the front pocket. Same idea, less commitment, and it survives a whole night of trick-or-treating.

A gardening costume also ages well. The overalls and hat go back into normal rotation on November 1, which is more than you can say for most of what gets worn once.
How Much Does a Garden Family Costume Cost?
Around $10 to $20 a person, and the gardener is the cheapest of the lot because it is mostly closet basics. The kids are where the money goes, and even then it is craft foam, cardstock and poster board rather than anything bought as a costume. A pack of multi-colored cardstock covers every flower in the family.
For comparison, a bought kid’s flower costume runs $30 to $40, so the girls alone would have cost more than the whole family’s supplies put together. There is barely such a thing as a store-bought gardener costume, which tells you most of what you need to know about how little it takes to put one together.
The Bottom Line on a DIY Gardener Costume
This garden theme is fun, colorful, and whimsical. Everyone can move easily, nothing is fussy, and the pieces are comfortable for a long night of trick-or-treating. From my oldest to my youngest, they all loved their costumes. And the best part, everything is budget-friendly and comes together fast, even if you are starting at the last minute. This garden theme family costume is fun, colorful, and whimsical.
It is a DIY family costume that scales well for big families. You could add more gnomes and flowers, or even expand into insects like butterflies and bees to keep it whimsical. You could even add some family members dressed as veggies for a funny, but still cute element. There are so many options for large families with this DIY family costume theme.
Garden themed costumes have one advantage over most group ideas: nobody has to be recognisable as a specific character, so a toddler who refuses their hat at 5pm is still clearly part of the theme.

DIY Gardener Costume FAQs
Poster board, craft foam, hot glue and elastic will get you through an entire family. The flower petals and pot skirts are cut from poster board and cardstock, the gnome hats are rolled cones of craft foam, and the fertilizer shirt is foam shapes glued to a plain tee. Nothing is stitched and nothing needs a pattern. The only skill involved is cutting a circle, and the kids can do most of it themselves.
Poster board, cardstock or foam sheets for the petals, more poster board and some fabric for the pot skirt, and elastic or ribbon to hold the headpiece on. A hot glue gun does all the joining. We started with one big pack of multi-colored cardstock and it covered every flower in the family, which is why this is the cheapest costume of the group at well under $10 a child. Full steps are in DIY Flower Costume for Kids (No-Sew Tutorial).
Roll a cone from craft foam, glue the seam, and trim the base flat so it sits straight. Cut the beard from faux fur in a rough triangle and attach it with elastic that loops over the ears. The whole thing takes about twenty minutes a child once you have the shape right, and it is forgiving because a gnome beard is supposed to look shaggy. Full steps are in How to Make a Garden Gnome Costume for Kids.
Yes, and that is how ours was made. Cut the letters and shapes from craft foam and hot glue them straight onto a plain black tee. Foam is more forgiving than vinyl because a slightly crooked letter reads as handmade rather than as a mistake. Full steps in DIY Halloween Costume T-Shirt Without Using a Cricut.
Roughly $10 to $20 a person, and the gardener is the cheapest of the lot because it is almost entirely closet basics. The money goes on the kids, and even then it is craft foam, poster board and cardstock rather than anything sold as a costume. One pack of multi-colored cardstock covers every flower in the family. A bought kid’s flower costume runs $30 to $40, so the girls alone would have cost more than everyone’s supplies put together.
Plan one evening for cutting and assembly. Flowers take about 45 to 60 minutes each, the gnome hat and beard take 20 minutes, and the fertilizer shirt takes just under an hour. Get everyone to pitch in and help!
Overalls, a neutral long sleeve top underneath, and a wide brim sun hat. Everything after that is props rather than clothes: garden gloves in a back pocket, a trowel or pruners in hand, and a small potted plant to carry. Brown eyeshadow rubbed into the knees and hands is what makes it look worn in rather than bought.
Usually yes, and that is the whole appeal. Most people already own overalls or denim, a plain top and a hat of some kind, and the gardening props are in the shed. If you are missing the overalls, a canvas apron over jeans does the same job. Ours came together from closet basics plus what was already by the back door.
