The tee-shirt in the tutorial was made out of an adult shirt, but I figured I could do it even easier with a youth small size. If you have scissors and a sewing machine, you can make this!
Here is the shirt:
I took a 3T dress with simple shaping, folded both the dress and the tee shirt in half:, and laid the dress on top as a pattern:
Here it is cut out:
And all I did was sew up the sides, stopping at where I wanted the armholes to be. I was going to do a bit more shaping for the arms when I first planned making this, but there is a pattern on the back of the shirt too. If I did anymore shaping that design would have been cut into.
Turns out that a youth small sized shirt is the exact same length for a toddler 3T dress. I'm hoping it looks more 'dress-like' on Maggie. On the hanger, it just looks like a tee shirt with the arms cut off! I'll try it on her when she gets home - if I have some space, I may do a little more shaping in the waist to make it flare a little more... but I know that she will love having a special baseball dress for the game on Sunday.
And if it really looks silly, it was a free tee-shirt and took me all of 10 minutes to make.
