My tips to choose underwear for a long backpack trip:
1. No push-up bra
2. Comfortable and easy to hand-wash material
3. No frame for bra
4. Soft and easy to dry
5. Bikini style underwear makes you feel comfy and fresh
6. Soft and body fit lingerie-style bras are the good choice, that way you can have all ‘action’ and No need to worry about ‘controlling it’
7. Colorful underwear! It will brighten your backpack and how much ‘feminist’ you feel you are
8. Standard shapes (never bring thongs)
9. At least 3 bras and 5 underwear items so u can do hand wash
10. All are different colors and easy to mix – match items :)
Cheers.
