i made this for my sister as a christmas gift and then forced her to play hipster model. it's a simple and ridiculously affordable diy. in the past we've added pockets some plain target v-necks, but we changed it up a little for winter. there was a little more fabric to work around this time so my square of fabric for the pocket ended up being roughly 4x4.5 inches before folding and sewing. better watch out, this is such an easy way to customize our look that we might start adding fun pockets to everything!
