Yellow is my favourite colour and I like to have as many yellow dresses as I deem necessary. I want a short yellow dress now because I already have a long one and a two piece. The first two dresses are about double the price of the last one but I'm thinking one of them may be worth it. Which one is the best?
Edit: should have mentioned this but I know #1 is too small. They didn't have my size to try on in store so this is one size too small
Edit #2: I'm surprised that quite a few people are saying the other two are also too small. I'm wearing my usual size in two and three (small) and I haven't gained weight recently. But I must look worse than I thought 😅 I won't be purchasing any of the dresses.
Thank you to everyone who shared your thoughts/preference, I appreciate it 😊

I will be attending an outdoor music festival later this month. Trying to decide on an outfit. I'm leaning towards number 1 but my friends prefer number 2. I also surprisingly liked number 3 but I think it's too white and too fitted for an outdoor event. What do you think?
EDIT to add: Number one is a dress. I saw lots of comments about it looking like a swimsuit. Because of the fabric I don't think it reads "swimsuit" in person. Number two is a one piece but has no back and a zipper in the back of the shorts so it wouldn't be super difficult to use the bathroom.
