My wife is about 2 sizes smaller than me so there is no sharing (the DADT arrangement is probably the bigger reason we’re not sharing). My wife’s taste has certainly influenced mine over the years and vice versa. I buy her a lot of clothes (because she’s my wife and I like doing that... and also because there’s a bit of a projection going on). We have similar taste in style but there’s a definite difference in aesthetic. We’re equally feminine.
