I have NC for this I am not a troll.
In a few weeks I get married for the second time.
My sister tbh is being a bit of a cow 
She is coming from abroad (within the EU) but arriving 2 hours before the ceremony and leaving first thing the next morning as doesn’t want to take her (not secondary school age) children out of school. Had a bitch to my mum about why I wasn’t getting married during (their) school holidays - my STBOH is in the military and wouldn’t be here then.
In view of the military connection there will be several guests and groom in full military regalia. DSIS messages me asking if it’s ok for her children to come in jeans as have no smart trousers. I suggest this is a little casual as it’s a wedding.
I offer clothes that my own children have grown out of (DSIS is not hard up) she accepts, then declines then says she is borrowing clothes from someone.
Then there is another problem with clothes for the kids (after I ask what colour button holes to order) and I ask if there is some financial difficulty and can I help and she says no she is just trying to avoid spending a fortune on “just one day”
ffs it’s my bloody wedding and they are family.
AIBU to think she’s being ridiculous - it’s a couple of pairs of trousers for two pre teens.
