Why dont they dress their age?

I know of some ladies, no, no I should call them women, that refuse to dress their age. Let me share with you:

There is this woman I know, she is 57 years old, about to be a mother-in-law, and do you know what she wears? Well, when she came to my home for CNY to pai nian (she works for F-I-L), she was wearing tights and a pink baby doll style blouse! When I saw her, the first thing I thought was - what? Is she having a mid-life crisis? Her dressing looked like one of those "kawaii" harajuku kids. Only that she is not! She has a son that is almost 30 years old, so why is she dressing like that? This is not the first time. The previous time I saw her, she was wearing a layered ruffled skirt made of lace and a tube top. Something that would appeal to my daughter "S". I dont even want to think about all the other times when we had a good laugh about her dressing.

There is another woman that I see in school whenever I pick my kids home. Her youngest son is the same age as "S", so she cant be that young (unless she started really early). My guess is she is mid to late 40s. M-i-l thinks she must be at least 50. Once, she was wearing this "retro" looking dress that ended some 8 inches above the knees (i.e mid-thigh). Her face looked like from the Sakura Ting era, and so was her dressing. Yesterday, she was wearing this black dress with red polka dots (the size of mandarin oranges), ala Bozo the clown style - with a huge collar. Sometimes she comes in boots. Yes, in this hot Singapore weather!

What's with these women? I keep asking myself: Why do they do it? Why cant they just age gracefully, and wear something more modest and befitting their age?

Is it me? - Am I a sour puss? Just because I know I will never be caught dead in one of those outfits, I just cant accept others my age (or older) wearing it? Am I too old-fashioned and ultra-conservative?

Or is it them?? Mind you, these are not those "ah sohs" who are not in touch with fashion. They deem themselves up-to-date and trendy, and travel frequently to the fashion capitals of the world. But look what they come back with?!??

I would like to think the problem is with them!! Sometimes I wish the fashion police would take photos of them and post them in magazines in the "what not to wear" section! I must admit though, that they always give me a good laugh!
