The long line hoodie has extra length in the garment, keeping your butt covered and giving you a longer line rather than chopping you off at the waist. The hood part provides a “youthful vibe” taking 10 years off!
And a couple of pockets to keep your hands warm.
The Pink hoodie and Grey pants work together as the 2 colours are very similar in tonal values, so it lessens the horizontal chopped effect on the body. This is reinforced by merging the colours into each other – ie taking the grey pant colour into the pink hoodie via the grey zip and the hood lining.
