Twice I have packed for an 8-12 week adventure, and twice I have failed miserably at the tedious task of packing.
I have Pinterested, read blog posts, and watched Youtube videos, yet in the end,
I still overpacked *(face palm)*
Here are a few suggestions to consider:
1. Ireland and Scotland are not as cold as you think, during the summer and autumn months.
2. You will only wear about four outfit combos and two pairs of shoes out of the twenty different pieces of clothing you try to cram into your suitcase.
3. There will be tons of shops with trendy Uk and/or Irish clothing, and you will get comfy enough to shop in them :)
4. Primark and H&M will have everything you forgot and everything you aren't sure to pack.
I normally stuck to leggings, light long-sleeve shirts, and athletic shoes in Dublin:
