My wife and I have different styles for the simple reason that what looks good on her wouldn't necessarily look good on "Leslie", and vice versa.
That said, it often happens that I will come across something that I think would look great on my wife when shopping for my female attire, but, alas, it is not to be. She made it clear to me years ago that she didn't want me to buy her items of clothing anymore the way I used to for past Christmases, birthdays etc. Somewhere along the line, she got the notion into her head that whenever I was buying something for her, I must also have been buying the same thing for myself since I liked the item so much, and the thought of that was just too "creepy" for her. Not true, but when someone "believes" something so strongly, it becomes an unshakeable article of faith for them.
Her loss, not mine, however.
Back in the days when my wife was working in an office (also back when women still wore dresses, skirts and heels in those settings as opposed to today's "athleisure wear") and I was still permitted to buy such things for her, she would often tell me about all the compliments she had gotten when wearing the clothing items I had given her.
Maybe i've actually answered my own question here. Perchance the "green-eyed monster of jealousy" led us to this point eventually...
