    1. Sushi


    Foodie moms, here's your chance to dress your little one up in one of the best dishes on the planet -- sushi! It's colorful, silly, and easy to DIY. Perfect, right? All you need is a white onesie and felt (in green, red, and black). Props for mom can include chopsticks and a bottle of soy sauce.  Check out mom Laura Izumikawa's Instagram page for more fun baby costume ideas.

    2. Princess Leia from Star Wars

    Take a cue from celeb mom Andi Manzano and Olivia and dress your little one up in your favorite Star Wars character. You don't need much for a Princess Leia costume for your baby girl. Attach rolled thick black cloth to a black headband, pair a white robe or big button down shirt over a white onesie, and you're good to go. Don't forget the lightsaber!

    3. Aerobics teacher

    Let's get physical! Here's an easy costume to put together. You need a long-sleeved onesie, leggings, an elastic headband and leg warmers (or high socks). This idea comes from mom Jill from the blog Homemade By Jill. She opted to make a felt boom box to go with her daughter's costume but playing the song “Physical” by Olivia Newton-John in the background works too. 

    4. Finn from Adventure Time


    Pinoy parents Cathy and Gino Roberto love dressing up their son Ringo as pop culture characters ever as a tiny baby. To mark his first-month milestone, they dressed him up as Finn from Adventure Time! Just like Ringo, you'll need a blue onesie, Finn's hat (try the nearest Comic Alley store or crochet your own using this pattern), and a toy figure or plushie of Finn's best friend Jake.

    5. Pineapples


    Would you agree that this is the cutest pair of pineapple you have ever seen? Felt is your friend if you want to DIY this costume. Copy Amber Yong, mom of twins Leia and Lauren in the photo above, and top your baby's costume with a bright yellow tie-on headband. The Singapore-based mom loves dressing her daughters up in the most adorable get-ups! Read our interview with her here.

    6. Tuxedo

    How would your baby like his bottle: shaken or stirred? Your little one will be the most dapper of all on Hallows' Eve in a tuxedo onesie. You can choose to sew on white felt and dad's bowtie on your child's black onesie or order the above from the LindaSumnerDesigns Etsy shop. 

    7. Cow

    If you've got a bit of extra time, make this super cute cow costume for your baby. You know, because he loves milk! There's a little sewing involved, but it even comes with cow ears and udders (yup, using bottle nipples). Moo-rvelously udder-able! Find the instructions at Make It & Love It as prepared by mom Ashley.

    8. Karate Kid


    Here's another costume from mom Laura Izumikawa and you probably already have all you need to whip this one up. If you’ve got the white terno and black belt settled, you can use a black marker to draw your chosen design on a white strip of cloth. Practice your child's “wax on, wax off” technique when you're done. Read our feature on mom Laura here.  

    9. Ice cream sundae


    We just can't get enough of twins Leia and Lauren. Here they are as cute ice cream sundaes -- complete with sprinkles on top. Aww! To DIY this costume, a white onesie, a white beanie and a tutu are all you need plus a little bit of time to sew or stick on the felt details (i.e., sprinkles and chocolate syrup). Make the cherry on top with the help of this tutorial from Primary.
