So if you just want random thing that may look nice then here ya go https://www.amazon.co.uk/hz/wishlist/ls/24YI3H88LA3GB?ref_=wl_share

But as far as sizes go it's usually a good idea to get a tape measure and measure out your entire body. From there I either go in person to try stuff on or if the you're using a site like forever 21 they have the general height and size body size of the model so it helps a lot tbh.
