Is he attracted to me, he teases me so much..help?

He is really lovely, and he teases me about random things like my shoes, teasing me about the state of them when they were falling apart on several occasions, then when I wore decent ones for the first time he was like ‘oh glad to know you’re prepared to spend a few extra quid’ in a jokey way, and laughed, he was trying to amuse me.

Then recently I passed him and he said ‘nice hat’, with a smile, fairly quietly, i almost didnt hear it, but i turned and went ‘im sorry?!” really loudly, with a smile and he smiled back and carried on walking.

Also he commented on my new look in a positive way “you’re looking very stylish today”, while he passed me and he looked back to take a look at me again.

Then later he joked around saying i shoplifted, so thats where all my new clothes were coming from!
then when i looked offended (i was only joking) and started walking away, he got all worried and was like ‘i was only joking” but he was still smiling.

also, (sorry i keep rambling!) i have this one designer purse that was a really special present, he noticed it because it has the designer printed all over the front of it, and i had it out and he was like “oh, is that real or did you make a quick trip down to the market haha”, again, he was chuckling/smiling, so was clearly joking,
i acted offended again and he carried on smiling and was like “im only joking”

i don’t know what to think, i only met him recently, we aren’t close friends, more acquaintances, but i really enjoy his company and our little exchanges from time to time. it really makes my day, he is quite a flirt i guess.. but he does this to me so much. i really love it! haha
and he smiles at me, says hi to me whenever i see him around.

these are only very few of the examples i can give there are so many!

does he find me attractive or is this all harmless flirting? (as a side question, can you call this sort of teasing, flirting?)

thanks in advance
