I hate it when girls say men don't put in effort or don't care about their clothes some guys are obsessed with clothes more than us... Now maybe not me but some girls.
Over all I would say girls still beat guys when it comes to clothes because we wear more clothes all you have are tips and bottoms and shoes. While we have that plus dresses, skirts, boots, heels, accessories, hats, etc.
I change a lot it takes me about an hour to decide what I'm going to wear and later in the afternoon I might end up changing into something else.
I don't by a lot of clothes (because I'm really picky), nor do I change clothes throughout the day multiple times... If anything, I change into basketball shorts to troll around the house if I know I won't be out.
I feel like it's both. I've met some women who literally change 5 times a day for no special occasion, and I know some guys who wear 20 shirts in one day "just because".
I'm in college so you can imagine how little my wardrobe is xD I just change twice in a normal day: from my clothes I use to go to class, to the one's I use at home. If I go out at night I obviously use other clothes.
I don't have many different clothes, I have 3 pants, and less than 10 t-shirts. I wash them every week so they're clean, but I do get bored of using the same clothes, so I was thinking on buying new t-shirts/shirts, the problem is that men clothing is too expensive.
