As there are different seasons in the year and different climates in various parts of the world, it is important to consider this when you are shopping as this would keep you both safe and comfortable.
The season
If you are shopping for a friend and her children, keep in mind the climate your friend is living in. Although you may be experiencing winter this may not be the case for her as she could be experiencing summer. It will then be easier for you to shop as you know you do not have to shop for winter clothes. Purchasing outfits that fall into the category of girls summer sets will be a good purchase for a friend living in a hot climate.

Being mindful of the season before you buy a piece of clothing is a good idea because if not the outfit may not be worn. For example, if you buy a summer dress for someone living in a cool climate the outfit will likely not be worn until the person is ina suitable climate to wear the outfit.
Wear later
When you are shopping it is a good idea to purchase something that can be currently worn. Buying outfits to wear later may not always work out as planned. For example, you may fall in love with a dress or shirt and keep it in the cupboard to wear at a late time. However, there are certain factors that may get in the way of you wearing the outfit.
For example, when you do eventually decide to wear the piece of clothing it may not fit you as well as it did at the time of purchase as it could either be too small or too big for you. You may even find your likening towards the outfit has reduced which could prevent you from wearing it as your sense of style may have changed.
You could even forget that you have the bought the piece of clothing especially if it has been tucked away in your cupboard for months. Therefore, it is a good idea to purchase something that you can wear the next day as you will likely get more use out of the outfit rather than saving it to wear at a later time.
Keep warm
When you are dressing for a cold climate, it is important that you dress accordingly. Going out into the cold without the proper clothing could lead to you catching a cold. Therefore, to prevent yourself from getting sick, make sure you have the appropriate clothing for the climate you are in.

This does not only mean just purchasing a sweater and a scarf. If you are entering the cold, you will need gloves, boots and a snow hat to ensure that you are safe and comfortable in the cold weather. Especially if you are not use to the cold then you need to take extra precautions to keep yourself warm.
A budget
When you are on holiday the excitement of being on vacation and being in a new place could lead you to over shop. However, setting a budget will help to restrict yourself from overspending and instead purchase only what you really want and need.
