lol she sounds like my mother, give your wife the money to go and buy some new swim wear and don't let your MIL anywhere near the new ones :o)
I don't understand why she would do that. Does she not want your wife to wear bikinis? If that's the case, that's not really her place to be saying that.
when i saw this question it made me think about how my ex mother in law got tied up in my wife's swimming suits and under wear, we used to have a top loading washing machine when it stopped it had to be emptied the m-i-l leaned over to get the last items out she slipped and fell in I was laughing she was screaming pulled her out by the legs she was well wrapped in a stringy top
Is she a normal person? it just seems a strange thing to do and what was it that got you going?
