I like 1 just the design and color are nice together.
I use wish all the time and I've ordered clothes from there. I don't reccomend buying something that important that's a clothing item because it's a hit and miss with wish. For instance ordered a onsie for my friend that came in 2 sizes bigger than needed. A shirt for myself which was small and a jacket that came not as described. With that being said I've ordered other clothing items and things that came better than I can imagine.
If you can find the one you want on a different seller it may cost more but you get what you pay for and you'll have reasonable shipping. Unlike wish which takes on average 14-31 days and it's usually the later days.
All I can say is read the reviews carefully including the bad ones, and read the reviews for the store and item description thoroughly.
I wouldn't be as upset if I bought shirts and sleepwear for a really good price and got the wrong one or wrong size as oppsed to a tux for prom. Keep in mind a lot of those take professional pictures from other stores to sell their knock off products.
Going with Dress 4 because in a worst case scenario dresses like 1 & 7 with the extra designs will come in the mail looking a hot mess... the prices seem too good to be true lol and I've seen girls who spent like 15$ on a dress that looked fantastic online only to recieve a ragged mess
So I cannot say because I've never seen you so I don't know what will look good on you. But I just want to let you know that sites like these make imitations of those dresses, usually made by underpayed children and women in Asian countries. Can I suggest looking in a local thrift store/ second hand store, I plan to buy a dress from one for my boyfriends ball.
