Fat at 50 big birthday party - need to look glam Help!

[StrumpersPlunkett]

I am size 20 5ft7 tall. I turn 50 in a couple of weeks and party at the beginning of December.
I have looked all over and can't seem to find something that will be flattering to the larger tummy big boobs.
My whole family are slim and really naturally able to put outfits together, not a skill I have ever had.
If anyone can help I would really appreciate it.
Happy to splurge if it is the right thing.

Following as looking for virtually the same thing!

You’ve mentioned your tum but what are your favourite parts of yourself/colours? Any definite no-nos (ie. won’t wear a high neck/ short sleeves)?

Do you feel more comfortable in dresses? Jumpsuits? Trousers/skirt and a top? As someone else asked colours etc.
