LEWOTE2021 Matte Adult Graduation Gown Cap Tassel Set Royal Blue

I am 5’ 11” and I weigh 220 lbs. How can make sure the gown will fit my waist? I purchased one that was size 5’ 9” to 5’ 11” and it is too small

Is the blue cap/gown navy in color or is it a lighter blue?

Hi there, my son is 5'9", what size do you think I should order?

I received a 2019 charm, I paid for 2020... ? What now?
