It seems romantic and thoughtful to buy lingerie as a gift, especially on an anniversary. However, the task of acquiring beautiful underwear for your partner can be a lot more challenging than you might expect. The following straightforward guide will help you to please your partner and avoid awkward disasters.\nStep one: learn about her sizes\nIt is certainly useful to know your partner's bra size. Buying something that fits will communicate that you are being attentive, and an ill-fitting bra will need to be returned to the store. However, if you only learn one size, make sure it's her dress size. If you buy panties in the wrong dress size, you could end up receiving a furious tirade instead of gratitude and appreciation. Specifically, panties that are too small could leave your partner feeling self-conscious and humiliated when she realized that she can't fit into your gift. Worse, over-sized panties suggest that you see your partner's body as larger than it is, which will hardly make her feel sexy or appealing. In sum, the first thing you need to do is peek into your partner's underwear drawer and make a note of the relevant sizes.\nStep two: give some thought to her preferences\nRemember that your preferences might not be in line with your partners. For example, while you may enjoy the look of a satin thong, she may find it incredibly uncomfortable or trashy. Alternatively, that classic white bra that you like might seem boring or matronly to her. Look at her collection of lingerie and think about what might fit into the collection without merely duplicating what she owns. When it comes to panties, examine the cuts and shapes of her favorite pairs and try to find gifts that match these designs.\nStep three: flatter her figure\nYou probably know which parts of your partner's body make her happy and which parts draw the most self-criticism. Take this knowledge into consideration when buying lingerie, and make sure that you choose items that will flatter her shape. For example, if she is proud of her flat and toned stomach then a thin slip will make her feel attractive. In contrast, if she always complains about having short legs or dislikes her thighs, sheer stockings might not be the best call.\n Step four: think outside the box\nRemember that you are not restricted to buying bras and panties. There are many other types of lingerie that could delight her and add something interesting to her collection. Corsets and basques can be bought for women of all sizes, and they enhance the bust while narrowing the waist (creating a gorgeous hourglass shape). In addition, some of these pieces can be worn with tailored trousers or a flowing skirt, so they could also be used to make sexy new outfits that work outside the bedroom.\nStep five: err on the side of caution\nEven with all of the above tips under your belt, it is always smart to plan for the worst. Make your purchases from stores that have a lengthy return policy, as basques, corsets and bras can usually be taken back.
