Clothes shopping in Dublin can vary widely. There are the usual chains: H&M, Wallis, Topshop, New Look (the two floors one in Jervis) and Penneys. These are the regular spots to hit if you''re looking for something nice, relatively cheap and a regular look. However, if you want something a bit different, you can go to Bershka, Forever 21, Om DivaUrban Outfitters (Beware: the purse must be bulging if you want to buy anything in these places!).
If you''re looking for a cute little top, try No Name on Dame Street - very cheap, a tad tacky but can have quirky stuff. Also good for dungarees, or leggings.
For ''alternative'' (chain) fashion, head to Urban Outfitters. It''s generally very expensive, but you can find nice accessories on sale by the tills. Another shop that''s very quirky is Lucy''s Lounge in Temple Bar. A lot of the stuff in there is lovely, but insanely overpriced. I once bought a dress in there, and when I wanted to return it, they told me there was a strict no-returns policy. So buyer beware! Any shop that calls itself Vintage may as well say rip-off!
H&M is your best bet if you need an emergency top/pair of jeans. Also has very cute, cheap accessories. It would be a good idea to have a plan of where you want to go/what your budget is as Dublin''s high streets can be so disconcerting, and it''s easy to find yourself going constantly back and forth. No matter what you''re looking for, you can find it in the infinite choices of Dublin''s fashion shops.
