<human>: I've been dating my girlfriend for three months now. Normally her style is pretty nice – simple/classic, like lots of one colour things, yeah I guess pretty simple and stylish. 

She has this ONE dress though that I fucking hate. It's such an eyesore – its got otters all over it in like sailor hats and boats and that sort of thing. Think SUPER childish. The print is so busy, it makes me feel like my girlfriend has turned into a where's wally book. She honestly looks like a character out of a kids book in this thing and I have no idea why she is so obsessed with it. It wouldn't be as annoying if she only wore it occasionally, but it's literally her favourite dress. Like the first one she puts on after a wash – she would absolutely wear it once a week. She doesn't wear it to work though, she only wears it in her free time so she wears it ALL THE TIME when we're on dates. 

I just find it really embarrassing. It's such a stupid childish dress and not appropriate for nice dinners and shows and stuff. I've tried to be as diplomatic as possible here – I've said stuff like "I love your blue dress, why don't you wear that tonight" and sometimes she'll take my suggestion but other times she'll be like "no I want to wear my favourite one!!" and so that's what she wears. It annoys me she doesn't take my feelings into consideration seeing as though she's going on the date with me, so surely she wants to look good for me?

She loves it because otters are her favourite animal, but I don't get it. I fucking love tacos but I'm sure as shit not going to wear a taco print jumpsuit out to the movies. 

How do I tell her it's ugly without hurting her feelings and making her mad at me? Because at this point I'm honestly considering giving it to my dog and claiming it was an accident when he shreds it.

Can you condense the text into three sentences or less?
<bot>: my girlfriend has a butt-ugly dress and wears it all the time. How do I get her to stop?
