Vintage Blue Schoeller Skifans Ski Pants Size 6

Love these but they are too small for me 😭😭 I typically wear a size 29/30. It seems these would best fit a 27/28 Note that these are marked a size 10 but are vintage and run small. Measurements and additional details are in last photo! It says 15 inches but a 15 inch waist always fits me these were very tight and not stretchy. Questions? Leave a comment below!
