Funeral outfit help please

[SherbetDipDap]

I have a family funeral to attend in a couple of weeks. Close family member so likely to feel a bit ‘on display’. My DGM hates tattoos so I tend to dress very modestly around her as it’s not worth upsetting an old lady. I’m sure she knows I have tattoos but I’d rather not rub it in her face on what will be a sad day anyway.

I’m 5’6, curvy, 12-14, somewhere between hourglass and pear shaped - I’ve seen it called cello shaped? I have blue eyes, warm toned dark blonde/light brown hair and usually look good in light or bright greens, blues, pinks and purples.

Please help me find something that covers my arms, shoulders and legs, in a dark/muted colour, that doesn’t make me look like a nun! I don’t look my best in black and don’t think it’s really expected. I was thinking of maybe a waistcoat co-ord with a long sleeved blouse? I tend to run hot so bonus points for light/airy/breathable fabrics.

Budget is flexible but I’d rather not spend a fortune as I have a husband and kids who are as scruffy/casual as me and will need dressing too.

I'd try to borrow something suitable from a friend, it seems a shame to spend money on something you're unlikely to wear again.
Failing that, I'd go for a dark blue/green aubergine if you don't want black. You can easily find trousers to wear with a darkish top, or indeed any top if you were to wear a jacket of some kind on the top. Or a dress with tights and/or boots to cover any tattoos you want to hide. A dress could even be patterned.Might be too £££.
