There's a blue mark from a ball point pen on my new satin bustier top - the kind usually worn for formals paired with a skirt. The mark is 3/4" long but not clearly visible since it's almost near the side seam. Is there any way I can get it out? The material is polyester-lycra and it's silver/light grey in colour. I did a search but it only turned up pen marks on bags, not clothing and I'm afraid if I try those tips it'll damage the material or affect the colour of my top :s I hope someone out there can help me, TIA!
