Making a Dress - Decision to make

My timing has been messed up this month for "Making a Dress" because of a delay with postage of the last project so I have only a week to decide which one of the following I should make.

Should I make the dress on the left which is a sort of overdress that ones wears over another dress/outfit like an apron or the one on the right which is a empire line/emily temple style dress.

I am torn between the two as the one on the left looks very cute and I can use it to co-ordinate with other things in my lolita wardrobe.

But the one on the right would be wonderful for the summer and it is a nice for a casual lolita dress.

What do you think?
