Hi there! Just my kind of topic!

It's definitely not too early to plan! I always purchase my bathing suits in the winter because that's when they go on sale. I have purchased many from VS and I actually just purchased that same one (flower) for my upcoming cruise...It's has not arrive yet but I have an older one that's very similar. The plunge monokini doesn't have much support so it's better for someone's who's not busty. I got the Size S and it fit perfectly!
There are a lot of ebay stores that sell monikinis as well. Hope this helps!
As for other VS pieces, I really like the Push Up Demi Triangle beceause it has support and gives you an extra cup size. It's really amazing on...
