A t-shirt dress in orange is basically a long t-shirt and that is exactly the point. The fabric is soft and comfortable and the fit is straightforward. Orange in a t-shirt dress reads as casual and friendly rather than formal or costume-y. The simplicity of the construction means the fit and fabric quality are everything. Throw this on with sneakers or slides and you have a complete outfit. These are the orange t-shirt dresses that work because they ask nothing of you except to wear them.
