Moneywise we are fine. I've got a good, secure wage (well for the next 18 months I have), we are able to save and don't have any expensive habits. Our clothes are almost all supermarket, but I have spent 'well' on the classics - a very good coat, nice suits etc. Clothes that are still going strong almost 10 years down the line - so if you saw me dressed for the Mess you'd probably think I had more money..
Our home is cheaply rented, but has good solid furniture that will last and looks better the more 'lived in' it is. When we buy our biggest extravagance will be the kitchen, because I want it built to last and not date too badly.
I do have an iPad (raffle prize - I had a thread on it), iPhone £40 a month and DD has my old iPhone she uses as a games engine. But DHs phone is a brick that is now 9 years old. He gets a new one every year but passes it on to his DD because he doesn't care for technology.
My contract finishes in 2014, and if I don't find work straight away I will be taking home a 1/4 of my current wage in a pension. But I'll still have those good quality clothes, technology and furniture, so people may think I have more
One of our 'expenses' though is helping our parents - both sets on pension only and with health problems. They won't accept our 'charity' but we are able to buy things / fix things and they don't always know about it (we replaced my DPs fence last year, but they think it was the neighbours!). I'd say that between them they 'cost' us a couple of hundred a month. We would give up a luxury before we stopped helping them.
To look at them though you'd think they were minted. My DPs drive a 2003 plate 'flash' car - I gave it them and pay the minuscule insurance. They spend weeks at a time at our caravan - but it's cheaper to heat then home, and what's the point in it being empty? They have a big house with a large garden, but it needs lots of work. DPILs have a huge house, but it's in a very cheap area and they don't use the top floor. The have a lovely new car - courtesy of DLA. DMIL dresses fabulously, but her clothes are years old and only worn at home (she can't really leave the house any more). They have sky and 2 large flatscreens, but when your only entertainment is TV then it is a blessing.
Looks can be deceptive OP. People may not be as well off as you think.
