The end of summer triggers nostalgia for the fall holidays and Halloween usually kicks off the season for many. As parents and caregivers of twins, we spend a lot of time each year thinking of the perfect costume combination, especially when the twins are very young and still allow us to make the decision.

I remember the first costumes my boy/girl twins wore. They were about 10 weeks old and I stumbled across the cutest and inexpensive Casper the Friendly Ghost onesies with matching bibs. Over the next three years, I would have so much fun 'pairing' them in themed costumes. At age one they were Barney and Baby Bop. The next year, I searched long and wide to find Batman and Catgirl outfits small enough for them, and I did. Three years of age was the last year they allowed me to dictate their costumes and they dressed as pink and blue Crayola crayons.

Once boy/girl twins reach post-kindergarten, it will be almost impossible to convince them to dress in themed costumes, their tastes will begin to be completely different and dictated by their own gender. At this point, just let them express themselves and have fun watching them enjoy the traditions. Same gendered twins, however, will often dress in matching or themed costumes much longer than their mixed-gendered counterparts, and as long as it is the choice of both twins, enjoy it while it lasts.

Since Halloween is fast approaching, check out some costume ideas for twins aged from birth to teen.

Teen Twins
It's fun to see teens enjoy Halloween and dress up. You may also find that mixed-gendered twins 'rediscover' each other and find it cool to dress in themed costumes, like Fred and Wilma.
Also, teens tend to lean toward more adult costumes, such as disco queens, so you could suggest that your teens form a group with other kids and become a rock band or a cheerleading squad or a basketball team.
