For sure buy linens there, the israeli beds are smaller, so it is not worth bringing your own linens. If possible, try to find a seminary girl/ yeshiva bochur, who can give you their linens from this year and then you can pass them on to people you know for next year, that is what I did with my linens. If your unable to track down linens, go to websites like yeshivalinens dot com
Cooking utensils, some seminary girls such as girls at Darchei Binah, michlalah, and MMY are required to cook two of their own meals daily, and therefore most likely have pots and pans you can buy off of them or they can give you.
Clothing, Israeli summers are EXTREMELY hot. You only need a light sweatshirt for the evenings, you really only need a few white shirts, but beware, dry cleaning can get expensive, so try to bring shirts that don’t need dry cleaning or ironing. Skirts, five black skirts should be fine, and one of a different color, one pleated, one slinky skirt, one a line skirt, one pencil skirt, one straight skirt, and whatever color one you want (that means six skirts). Shirts for women, make sure to bring shells, they are most important to bring large amounts of because israeli shells are not such great quality. Two black sleeveless, two white cotton three quarter, one white for shabbos, two black three quarter, one black for shabbos. Layering shirts, tanktops take the least amount of space…
Sefarim, bring a few in your carry on, I would say instead of all of mikraos gedolos for all of tanach, just bring an art scroll tanach, the smaller siddurim are easier to carry, but if you plan on buying a new siddur/ tehillim or want to engrave one, then you should bring the one you usually use and have it engraved. Most English sefarim are available there in geula. I am not a guy, but I feel like you really only need the masechta that will be studied at the summer point of the daf yomi cycle, otherwise its way to much to bring all of them.
Personal care products- Israeli products are specifically meant for their water, its a waste to bring american shampoos and conditioners, phinok is a great brand to buy. Deodorant is expensive there, so are menstrual supplies, but if you don’t have room for those things, you should buy them when you get there.
Also, shirt for kriah when you go to the Kosel.
I hope this helps.
