First things first, let's leave the "swagg" thingie to teenage girls. Men have style
Now to the topic, when you improve your looks, body language, the way you carry yourself, you can expect to be opened by women more (freaked me out the first time I got day time cold approached by a woman lol!), or at least you'll start noticing a lot of signs they would like you to approach her (smiles, subtle staring, hovering around you, etc.).
I wouldn't draw any conclusions from a single situation, but the fact that you became more mindful on improving your appearance is a good start and means you're on the right track. You'll get better with practice.
Some quick tips:
-Always cover the basics: wear only clean clothes that smell nice and fit you.
-Most guys dress waaaay too loose: if you want to look hot - tighten up.
-Most guys dress too plain/boring: khakis, polo shirts, bland colors, etc. It works fine for business casual, but you're dealing with women, not business clients. On the other hand, don't go overboard with peacocking, no point looking like a clown who's out of work.
