There are sales all over right now, and sometimes it’s hard to figure out what to go for. Here are some keywords.
Quality In stead of buying lots of cheap stuff extra cheap, go for quality. This is the only time many of us can afford some of the more pricy stuff, and usually the quality is way better.
Shorts We have seen these in stores for a while, and they will be just as trendy next year. Grab them while you can!

Leather handbags The tan leather handbags will work next year as well, but black leather will last forever. Mango has a nice handbag that looks a little Chanel on sale right now.
Winter coat These can be expencive so buy one now while they’re on sale. There’s still some months of cold weather to get through (at least in Norway). Also look for a trench coat for spring if you don’t already have one. There’s nothing more timeless than that.
Jeans Also a garment that can cost quite a bit, so look for them now. Last sale I bought an extra pair of my favorite. Remember that the waist is rizing, so don’t go for the low ones.
Knits Woolen sweathers and any sorts of knits never go totally out of style, and there are tons of them in stores right now.

Shoes Nice heels won’t go out of style too fast. Platforms will last another year, so look for those as well. Sneakers are also great to get on sale. Above are semi-expencive heels from Mango.
Basics and classics All sorts of basics and classics that aren’t mentioned above. Suits, white shirts, black pumps…
Think spring Take a look at the spring collections and have a look at what colors and styles you would like to go for. Some of this you will be able to find at the sales now.
I always check out Mango during the sales even though I never shop there normally. They have some semi-expencive stuff in good quality, and usually have the best sale of all.
