i would love to wear a dress and that one looks lovely but i agree with some of the others, a better bra and maybe you would feel better in one size bigger if it feels tight or clingy. i have put on weight in the last 2 years, i was already a size 20, my problem is everthing is hanging down, i had to go to a doctor about my vulvar cancer and having all my lymph nodes removed from my groin, he said it would be difficult to heal as they are at the top of my legs and the fat hangs over...lol, i only ever wear straight leg jogging trousers because i have severe psoriasis and it cuts and breaks whenever i move, i always wear nice t-shirts and tops and always get a size bigger than i need. i have got a couple of those knicker type things hat pull everything in, just in case i need to wear a skirt and blouse for a funeral. please scentia, wear clothes that you are comfortable in, if that means jeans, a fancy top and some make up, then go for it, this is all about how you feel, it does not matter what anybody else thinks. when you buy something new and are not sure, take some pics and send them to your daughter for an honest answer..lol
ps. i am now a size 22/24 so i would be so envious of you in a size 16. xx
