Most of us would love to have a lot of clothes but can’t afford. Being big size I used to have my clothes sewn, I was ashamed to wear jeans or blouses. As soon as I lost some weight but still big size I was able to buy different blouses and a few dresses. What I did was have a black skirt and some jeggings or harem pants. Some people would barely notice the skirt but it is the blouse that attracts. So it would be cheaper to buy a few blouses and have the reliable black skirt. If you can also have a blue (dark) and a dark brown skirt. These usually matches any colored blouses. If you wore a certain blouse with the black and it also matches the brown, next time wear it with the brown skirt.
Accessories can also change the way you look. It won’t be noticeable if you wore the same blouse but this time you have a necklace or pretty earrings so the eyes of the person will look at the jewelry first. Also having a new hairstyle can help. Nice make-up and nice perfume too can attract the person you are talking with to something else than your clothes.
In dresses it would be the usual little black dress or bis black dress. It makes you look slimmer. And again accentuate with jewelry or other accessories, make-up and hair do helps too.
When buying blouses if you are big sized dark colors, or slanting lines design are good. A dark skirt and pants or leggings are also helpful.
The most important thing is to wear your clothes with pride and as if you are wearing a most expensive piece of clothing. Wear your clothes with confidence and you will look confident.
