This one below looks very sporty and vintage meets modern kinda thing. Although this trend wouldn't really last long, which means it's only a one season look thing! Also this particular look wouldn't suit many occasions, the one occasion I could think of that would suit is dance battle, because it is very urban and street! So I wouldn't wear it too many times even though it looks pretty awesome! :P
This next look is also another one-season-only look, that big/butterfly arms/huge looking shirts or tshirts. I have to say if the knitting (quality) is good, then when worn it would look good, unfortunately not all body types can suit this kind of look, before you buy something like this you really need to try it on and see whether it looks good on you or not, otherwise it'd be a waste!
This kind of tops can be worn with anything; high waist belt, highwaist skirt/shorts/pants, hipster belt or normal hipster shorts/skirts. Again it depends of the look of the top!
