We have been friends for about 3 years. In the past year or so she's becomes obsessed with "fashion" and basically spending shit loads of money on ridiculous items. She comes into work saying stuff like "oh I've seen the most gorgeous coat, it's £485 though" she then waits for the shock response and then adds "but I love it so much - my husband said he doesn't mind if I get it" she waits again for a response and then adds "but it's Soooo expensive" blah blah on and on. So she buys the bloody thing and then starts going on and on about some new boots she's seen for £500 - same thing again - "oh but they're so expensive - oh but I love them - oh I don't know what to do - I can't stop thinking about them" on and on and on.
But then the really cringe worthy bits come when she says things like "Oh I really want this Superdry jumper I've seen - I mean, when you wear superdry people KNOW it's expensive, that's why I want one" or "I prefer the brown boots to the black ones as they LOOK more expensive and people will notice how expensive they are" 
To add - she then tells me they're struggling with mortgage payments
She's my friend and everything but aibu to find the whole "I want people to think I wear expensive stuff" a bit sad and tedious?
I mean - example of how ridiculous it is - our company was in trouble and there was talk of redundancies - we're all sat around moping and she sighs and says "oh I'm so stressed out" I'm about to agree with her and she adds "I can't make up my mind about those boots" ffs
