If old jeans need a little design, you can cut the trouser legs into irregular shapes, which is retro and fashionable. Or you can cut your trouser legs into raw edges, which is very sexy. Wearing a pair of high heels below can modify the leg shape and lengthen the long legs.
Personally, I like wearing sweaters very much, and all clothes are inseparable from sweaters. Because it is very age-reducing. If you have an old sweater, don't be sad. You can cut it into a short one that shows the navel and show the vest line. It's cool. I especially like this way of wearing it. You can wear leather pants and sneakers below, which is very casual and shows your figure.
Besides sweaters, there must be shirts at home. Especially the boyfriend's shirt, can come in handy, can be worn as a skirt, and you can wear high heels below, which is very feminine.
Also, you can't live without suspenders in summer. It doesn't matter if your suspenders are corny. Teach you a trick to become fashionable, that is, you can put a denim jacket on the outside, cut the sling to the navel position to expose the vest line, put a pair of jeans under it and a pair of sneakers under it, which is cool to wear.
We have a spare coat, which can be cut into short baseball shirts. It's very sporty, and shorts can be trimmed with burrs. It's refreshing and comfortable. It's a goddess.
The above is just a personal opinion. If you have other better ideas, you can share them.
