Are the clothes from Shade clothing exactly like shown on its website?

I am planning to buy some decent swim wear for myself from shade clothing, as I have seen on their website that the swimwear is quite descent and suitable for a 15 years old girl! Nonetheless, since I am a bit plump, I would like to know from you guys if the clothes that are shown on the websites are exact to their sizes and shape, as they are shown on the websites! I would be grateful to you for some suitable advice!
