Me [21F] with my boyfriend [31F] 1 year, we are having a fight about clothes and he specifically asked me to post on r/relationships to see others' opinion

Hello, everyone. Sorry for bothering you with a petty issue, but sometimes I can't tell whether my approach on things is really weird and controlling, or it's just basic human decency. I'm sorry, this is going to get very long, as I need to be problem specific and describe my feelings, the background, the event and the fight after.
EDIT: Accidentally listed boyfriend as a female, he's a male
BACKGROUND: (will be important later)
I'm currently visiting my BF of 1 year in Germany. Sometimes we live together, sometimes we do not, he's just settling down here because he found a job here 2 months ago or so. We both work as programmers, have above average wages, money is okay. I'm an unusual colleague most of the time - there are usually men in my field of work and women don't much care about their appearance. I'm fit, wear make-up, wear nice clothes, smell nice, etc, so I don't look like "the rest of the boys". I take pride in what I achieved, in being able to support myself financially, in being in a field that's not usually filled with women and it's not easy to get into.
EVENT: (yesterday afternoon)
We all went shopping for clothes with his friend [29M] yesterday. My BF said that if I like anything, I can choose it and he will pay for it. This doesn't really happen often and I usually don't receive physical gifts, so I was really excited for a new piece of clothing. I thought it was a really nice act, because we hadn't seen each other for 3 weeks and he obviously wanted to make me happy.
So we went around shops and I stopped in one and took out a leopard printed coat. It cost about 90 euros. I put it on myself, checked myself out in the mirror, pressed my lips together and said "Excuse moi, je suis francais" (Excuse me, I'm french). I then came to my BF wearing the jacket and I said "Bezahlen!" (which means "paying" in German). He laughed, took it off of me and put it back with the other coats and proceed to walk out from the shop without even looking at me standing there.
This left me kind of frozen, he didn't even ask if I'm serious or not, just walked away like that. I followed him then, he could obviously see that I'm sad. He asked about a minute later: "Wait, did you really want it?" I nodded my head but he didn't turn back to go and get it. He just pulled off some apology and we continued our journey. I was already left with no excitement as I felt that he's broken his promise to me, to buy me something I want, and I felt like my opinion didn't matter at all, so I wasn't even thinking he'd get me anything that evening.
Then we went into another shop, where he tried a jacket on. It had some neon orange particles and he asked how it looks on him. I said "Usually workers wear neon colors like those, so it reminds me of them, but the fit is okay, I think it looks good on you," and he proceeded to get it. Me and the friend also told him to try on another - kind of elegant - coat and we both said he looks great in it but he didn't buy it.
I browsed some leather jackets. I wanted to try on one with a nude color, which is the color he hates most I guess. It's this pink-brown-skin color, I don't exactly know how it's called. He said: "Oh, don't even try this one on." I guess you can imagine how it made me felt after the coat incident. It was just pouring more oil in the fire. I was already so upset at that point I just wanted to go home and cry (I'm oversensitive and he's not sensitive at all, I'd go as far as to call him cold and cruel). I didn't speak much for the rest of the evening until we 3 went to get a dinner and I got a little drunk and loosened up some. In the morning the negative feelings came back.
THE FIGHT: (an hour ago, this morning)
So I told him I want to talk about yesterday. I told him that I didn't like that he doesn't respect me and my feelings and won't let me buy/try on stuff that I like. I said that the kind of clothes he wears aren't exactly what I prefer on men (I prefer more elegant stuff, shirts, nice shoes, he's a T-shirts and jeans kind of guy), but that I never speak up against it because it's seriously none of my business, I want him to wear what he likes, I want him to feel comfortable and feel good. As long as his clothes aren't a disaster, I'm okay with them. I see that I have no right to tell him what to wear and what not, because it's his choice, not mine.
This is where our opinions differ. He thinks I should wear what we both like, and that he should wear what we both like. But the thing is - I'm so much more tolerant with clothes, I'm used to guys wearing anything and as long as the clothes aren't dirty or totally wrong size, I seriously don't care. Meanwhile he uses harsh terms as disgusting when describing the nude jacket I wanted to try on, or I don't want you to look like a ***** when walking next to me to describe the leopard printed coat. This hit me really hard, because as I said in the background, I take pride in my work and my ability to support myself. Those words obviously hurt me because I LIKE this stuff and I want to dress the way I like, not the way he likes. I don't think he would go out of his way to change 70% of his clothes just because his clothes are not what I prefer. But that's the thing. I might not prefer his clothes, but I accept them and I want him to feel good.
He also tried to pull off the "Don't even try this one on" as a joke. I don't think it's funny, I don't think it's a joke, I just think it's really mean and disrespectful thing to say. Trying a jacket on doesn't hurt anybody.
He's the guy I'm dating, if we go out and he wears a Pikachu T-shirt (he's got one, yes) while I'm covered in brand clothes, I seriously don't care. It's his style and his personality and he shouldn't be afraid to show it with me. I never wanted him to hide who he is with me. If who he is is a guy with beard wearing a Pikachu T-shirt, then whatever, It's whom I've chosen to date.
Now I'd like you guys to tell me how bad my approach is. I don't think I should force somebody else to wear what I want, be it a friend, a boyfriend, a parent, a hamster. I think the primary choice is theirs and they should feel good in their clothes; I'm just there for the second opinion, which I'll gladly provide without insulting their taste or personality.

tl;dr: BF doesn't like the clothes I chose yesterday, uses harsh words to describe them, thinks I should buy what he likes, meanwhile I never tell him not to buy things just because I don't like them and I think we should wear what we like. Am I wrong?

All this drama over a coat....learn to stand up for yourself WHILE something you don't like is going on....not afterwards.
Your initial response should have been...
"So you're really not paying for the coat after saying you'd pay for whatever I wanted? Ok...I'll remember that the next time I promise you a blow job"
