I feel like there’s hardly any artistic depictions of the “Rarity taking Fluttershy's measurements” scenario as I'd imagine there'd be, specifically in the "waist" variety. Plus, I didn’t want to be redundant and just do another bust measuring pic. Midriffs are my specialty, so I decided to do a waist one instead.
Also, Fluttershy always seems super embarrassed when being measured by Rarity. I’d imagine it’d be a regular thing, right? I wanted to go for a slightly different attitude about her, to keep it fresh from the “Oh nyooo she’s measuring me in my skivvies uwu >///<”. Like, Flutters, it’s practically standard procedure. Plus she’s your close friend and not some rando.
At the same time tho, Rarity should probably keep some thoughts to herself, just for good, ahem, measure…
Awkward service provider/client convo. Gotta love it.
