Would it be proper for someone who is 5'9" tall and a size 8 to wear a two-piece swimsuit to the beach?

What is the cutoff point with weight and size for this?

Yes, I think you would look great. Just make sure you will be comfortable in the bathing suit. I'm 5'11 and a size 10/12 and love running around in two pieces. However I'm comfortable. Otherwise, you won't be having fun if all you can think about is your body! But I think you would look great in a two piece.

Size 8 isn't big at all, especially for someone who's 5'9. I wouldn't worry about it. You probably look great.

I would think it's more about your body type and less about the size you are. I know people who are size 8 and fit.

Yes it would be fine.

It really depends if you feel comfortable or not. It also depends if all that is muscle or fat.

There is no rule about how much you need to weigh in order to wear a bikini. It depends on if you feel comfortable or not. There are many women who are size 8's and have good bodies. Just because you're a size 8 does not make you fat. I have a friend who has the same height as you and wears a size 8. She's big boned and curvy, but her stomach isn't round or has rolls...her stomach is actually really flat! She's just wider that's all.

So go for it! As long as you feel good then don't be afraid of what others think. :)

it seems fine as long as your comfortable with it

Well it shouldnt be what other people thing about you although we all know that it is. You need to feel comfortable. Look at yourself in the mirror, if you have a "muffin top" and your stomach is sticking out then you might want to switch to a tankini, but if you feel comfortable then wear it. Who cares what other people think! I think that from your description its fine!

why not? You can wear anything at the beach. You are fine as long as you feel comfortable with yourself.

i think you should wear whatever you want and don't let anyone elses opinion affect what you wear. if you want to wear a bikini, go ahead.

a size eight is not big at all, there are many people who would probably kill to be a size 8
