I bought a small suitcase and her suitcase is slightly larger

I bought :-
3 pairs of Jeans
1 pair of 'going out' trousers
7 t-shirts/tops
2 jumpers/cardigans
1 coat.
2 pairs of shoes/boots
1 pair of trainers and running gear -

underwear and socks for everyday and 2 'spare'
Her list :-
6 pairs of jeans.
2 pairs of 'going out' jeans.
9 t-shirts
5 shirts
3 going out shirts
3 pairs of shoes
2 pillows

Large hairdryer with diffuser.
millions of pairs of socks
many pairs of pajamas :shock:
3 plastic bag things that she packs stuff into and squeezes the air out of. :?
ummmm another rucksack of 'essentials' (I am not allowed to see what is in that.
She has a full rucksack of hairproducts and 'things'
She forgot... two 'essential' items - her sports bra. She figured out a way around this by use of a hair bobble and a double wrapped t-shirt. and...... her travel laundry basket. She made do with using mine (a sainsbury carrier bag)
Now, what I want to know.. is this normal ? Am I with some kinda freak or do people often take vast amounts of things when they are away.. things they will never use/wear/need?
