Male coworker often notices "new" clothing, does it mean anything or am I reading into it?

As the title says, a male coworker, who I'm friendly with but wouldn't go as far to say we're close, often notices new pieces of clothing I wear. Even when others don't.
I got a new pair of shoes and he commented on them, again, no one else noticed that day. I sorted my closet and found a light coat I haven't worn in a long time, perfect for summer showers, and when I wore it he asked was it new I explained yes, technically new to others but not to me and just laughed it off. Again, no one else commented. And when I got a new pair of jeans it was the first thing new noticed which threw me off, and he said he liked them.
I have female coworkers who I'm very close friends with who have gone the whole day without noticing these things, or I'd have to say "oh, I got new jeans" and then they'd comment, so for him to repeatedly notice these things, unprompted, could it mean anything?
