What to do about attention from younger man?

I (32f) go to the farmers market every week. My husband tells me I’m attractive to him, but when I go to the farmers market, I look a mess. Usually a baseball cap to hide my hair, very casual clothes… absolutely nothing revealing or flirty. Just a t shirt and jeans. And I’m just there for business. I get my produce and leave. I politely ask “how much?” And say thanks after buying produce but nothing else. I also always have my baby with me.

Randomly, a young farmer told me he thought of me when picking strawberries. And has been very sweet to me and gives me flirty smiles. I usually catch him staring at me and his face softens every time I approach to buy the produce.

Not fishing for compliments. It just made me wonder. What do men notice in a woman first? I thought with how casually I dress and mind my own business, I didn’t expect a younger (and good looking man) to notice me when I give zero attention to him.

So now, I’m just curious. What do men notice in a woman?

And should I be concerned? I do not reciprocate at all. I’m just polite. But I can tell he has some interest in me. I’m married. I’ve even brought my husband a few times, so I’m just confused.

Update: he’s not a social farmer. Very quiet and somewhat awkward. I don’t think he’s just being nice.
