Boyfriend said I dress like a grandma and wants me to wear tight clothing to a family photoshoot???

Ok so I have more of an elegant/classy style I guess you could stay? But I still dress my age I feel. I wear short dresses, sometimes tight dresses, I wear short shorts, crop tops, etc. Basically I like short things, but a classier look if that makes sense?

I don’t like too much (if any) cleavage showing. I don’t like my belly button showing, but my boyfriend does! He has told me in the past I dress like a grandma.

Today, we were talking about my style and I told him for our family photos I want to wear a nice flowy dress (maybe short or one with a slit?) and he told me to wear a tight dress, I told him I don’t find that appropriate for family photos. And how he doesn’t always want me to dress pretty, he wants me to dress sexy. I get it. But I find he wants me to wear tighter things at inappropriate times. I just don’t feel comfortable with that. He wants me to wear crop tops and have my tummy and belly button exposed. I don’t feel comfortable with that nor do I even like that look. He wants me to dress in street wear sometimes. I don’t like that. I don’t like graphic tees, colourful things, ripped clothes, etc.

So the problem here is we just don’t agree on my style! I was lowkey upset when he said he wants me to dress sexy because the man doesn’t even like lingerie! I find that shit so hot, but he’s told me in the past he thinks it’s pointless. So he makes me feel stupid for even wanting it, so I just never buy it...because I mean if I did and he didn’t care it would just be awkward?

Thoughts?
