/cgl/ - Cosplay & EGL

Trying to make pic related but I've never made a dress before. I think I've got most of it on lockdown by this point but I just want to double check.

For the skirt I'm thinking of making two a-line skirts (as recommended by someone here a while back) and having the one underneath be a bit longer so it sticks out with box pleats that are open at the bottom and then wearing a petticoat underneath that. Is that ok?

How to go about making pic related/similar patterns? I was thinking about buying http://www.aliexpress.com/item/New-Arrival-7-colors-Lovely-Princess-Sexy-Cosplay-Costume-Lolita-Style-House-Maid-Uniform-Restaurant-Server/2012470225.html?ws_ab_test=searchweb201556_1_79_78_77_80,searchweb201644_0,searchweb201560_10 since it's very similar and making a red bow and possibly replacing the four buttons on the apron with two big buttons but I don't know if the dress would fit since I'm a 6'1" guy so it seems safer to make it myself. Though it will be my first time sewing anything and I'm sort of lost.
