EUC Adult Grease/T-bird Sweeties costume -S/M

EUC Adult T-bird Sweeties costume - continuing my closet purge with this costume set I bought ages ago but never ended up wearing. 3 piece set comes complete with satin jacket, pedal pusher elastic waist pants & checkered neck scarf. Tags are a little confusing - jacket says S/M *and* medium/large, pants say medium/large (see photos of tags) but waist is not *that* big so I’d assume will fit S/M. Im 5’4” / ~115lbs and I bought it for myself - jacket sleeves are a little long but waist is smallish, pants seem a tad big 🤷🏻‍♀️ Comes in original packaging, no rips/tears/stains. Non smoking, no pets household.
