Wouldnt be a bad idea, although its the furthest thing from reflective interior.
You definitely dont want to attempt a stealth operation with one of those.
Id just build your own out of wood and black and white poly. Might cost a few bucks more but itll be reflective and custom to your size.
check out my mini cab in my sig. you can probably build one the same size as that wardrobe (maybe a little shorter) for $20 more.
Also im not sure how well the frame would hold possible heavy lights/reflectors.
Clothes are heavy and you can probably cram a bunch in there, but heavy metal and constant heat from bulbs could case things to bend more than anticipated. If you do go with the wardrobe id thoroughly test it before putting any plants in.
