/cgl/ - Cosplay & EGL

newfag here, how does sizing work for buying female cosplay for a guy
im looking at miccostumes and the chart says my bust and hips would be between M and L, but my waist being between L and XL
do i need to buy the biggest one just in case? that seems like it would be for fat women, and the bust would be loose as fuck, especially since i don't have boobs, tho from the user pictures it doesn't seem like the chest area is especially large
which one am i supposed to get, i know it's better to go a bit bigger than smaller
