    This pattern is so versitile! Great for undies for boys and girls, shorts under dresses,dance shorts, pj’s and so much more. I already have 5 pairs made for my 4 year old and quite a few more planned because they’re so quick and easy.

    Thanks for another great pattern!

    Great pattern. A quick and easy sew. I love the wide range of sizes. My kiddos love their boxerwear and are asking for more. I love that I can use scraps for most of the pieces, stretches my fabric budget a little bit farther. Now we have boxwerwear for the whole family!

    I love this pattern it’s so quick and easy. My daughter feels so comfortable in them under her dresses. She asks every night before her shower if I can make a new pair before she’s out lol

    I have been looking for a boxer pattern for my boy that fits him just right… and this fits him just right!! The construction for the seamless version is so cool and nifty to put together too. Definitely a worthwhile purchase to sew undies for years to come.

    This is such an awesome pattern! I love being able to make matching boxerwear for the whole family with this pattern and the mens/women’s patterns also available. There are instructions for mixing sizes to get the perfect fit for any child, should they happen to fall under a different size for height than for hip. And here’s a bonus for you: it’s a great way to make use of your scraps.

    I love this pattern so much. It takes me 25 minutes to sew from cutting to finish. Less if I do multiple pairs at once. So easy too! Great pattern to have in my arsenal as I have three boys. 🙂

    I was interested in this pattern for my 6 year old boy who only wears boxer briefs. I quickly discovered how ADORABLE these are on my two younger girls who are in diapers! How perfect for under skirts and dresses?! I sized up to fit over their diapers, and it worked well for both disposable and cloth! Another great pattern!
