Spyder Women’s Winter Jacket& Snowpants

Brand new Spyder jacket says size 12 but I am usually a 2 and It fits like a 4 would. Snow pants are gently worn for a year says size 6 but fits like a 4. Guess brand size runs big. Snowpants have a bit of red staining on the inside bottoms as to I am a Figure Skater and have red suede skates so from the ice It stained a bit. I’m sure can come out but I haven’t tried!
