The description says that this is a junior size product. I am an adult and I weigh 185 lb I ordered a large and these are perfect I don't like them loose and I don't like them tight. This material is perfect it is stretchable, unlike others that are made from cotton does not stretch and is very short above belly button. This style is perfect length perfect, fit perfect material, comfortable, soft and stretchy and the straps adjust in the front NOT in the back. The straps that adjust in the back are uncomfortable when you lay down they stab you in your skin. The fact that these are silk straps they do not roll twist or miss- shape and adjust in the front is exactly what I love. These are the only tank tops that I will ever buy again and I have purchased 14 other different types of tank tops from Amazon with shelf bras and none of them were even remotely close to suitable. Less than one star. These are 5 stars times 10, contrary to what other reviews say, these are the best you will ever get.  They came packaged individually and perfectly arrived the color that I ordered and I threw them directly into the wash after trying them on. This is the second time I have purchased these tank tops only because they were very hard to find. The first time I purchased these tank tops was 4 years ago and I still have those exact same tank tops but of course they are very worn out and I needed more. Now that I have received my second batch I'm ordering a third right now because for whatever stupid reason they aren't on Prime and I wish they were because these are the best tank tops on here. You can hold me accountable take my word
