You will probably already be familiar with push-up bras, they are designed to give your chest a bit of oomph, lifting and enhancing to various levels. They look just like a normal bra, except the padding is much thicker and can take up to around half of the cup space to create a fuller cleavage. However, while they can make a huge difference in shape, the padding is surprisingly discreet so you can wear them for any occasion.
One thing to consider when buying a push-up bra is that you should be able to adjust the straps to your desired fit. Yes, push-up bras are effective, but they must also be comfortable and you don't want them to gape. A wired, adjustable option is the best option for achieving a bustier cleavage. On the other hand, wireless push-up bras can still offer a moulded, perky shape and are generally more comfortable.
Are you on an endless hunt to find a bra that doesn't show through your clothes? The t-shirt bra is a comfortable every-day bra that gives you an even silhouette and its discreet seams help to hide the outline under your top. The cups don't stand out very much and they're moulded to a more natural shape in comparison to push-up bras.
This thin padding is a great option for small-chested people who want a bra that will cover the nipple without adding too much shape. If you're looking for a versatile, affordable option that you can wear pretty much anywhere, the t-shirt bra is the best option for you.
Bralettes are on the highest end of the comfort scale- if you don't particularly like wearing a bra, you will love how a bralette feels – it's like you're wearing nothing at all. Bralettes can be worn when you're lounging around the house and they can even be worn at work. They are easy to wear, as they just slip on right over the head without fiddly clasps and hooks.
A downside is that they're not usually adjustable so you can't change the length of the straps, although it's unlikely that you'd need to as bralettes are quite stretchy in comparison to other types of bras - but they can annoyingly ride up if the fixed straps are too short for you. Bralettes do not disguise your small bust, they emphasise the fact that you have a small cup size.
Cotton is one of the most appropriate materials for bras, which are garments worn against some of the most delicate areas of your body. It's soft, durable, and breathable so you can be comfortable in your bra without your skin feeling irritated or damp with sweat.
While it's super-silky, cotton can be a little bit more expensive than other high-quality materials, so you could consider synthetic fabrics such as polyester or polyamide. However, these risk becoming sweaty during hot weather. For a more affordable and durable material, modal would be a perfect fit. It closely replicates the softness of cotton, whilst being much more budget-friendly.
Of course, your bra can't be made from cotton or polyester alone – it needs some form of stretchiness in order to fit your shape. Elastane, lycra, spandex, and viscose are all popular elastics used in underwear. Think about it; if your bra wasn't elastic, it wouldn't stay closely fitted to your bust.
You need to have elastic in the straps so that you can easily stretch and adjust their length. In addition, a bit of elastic allows movement as you go about your day-to-day tasks. If you want to buy a bra that will last you a long time, 20 % or over of elastane will indicate a highly durable bra.
Unless you buy a bralette, which is traditionally a non-adjustable bra with a stretchy elastic to fit easily over your head, you should look for a bra with adjustable straps. Adjustable straps allow you to secure a tight-yet-flexible fit so that you can get the most out of your new bra.

The most important factor to consider when buying a bra is the size. Shopping for a bra can get confusing so it's best to measure yourself first. You can determine your bra size by measuring yourself at home and you'll be pleased to hear that it's a pretty simple process.
Find a flexible dressmaker's tape measure and wrap it around your band area, just below the bust and note the measurement in inches. Then, do the same thing with the tape measure over the fullest part of the bust. To calculate your actual cup size, round both measures up to the nearest quarter of an inch and subtract the band measurement from the bust.
After taking AA and AA sizes into consideration, every inch difference you count is another cup size, for example; 1/4 inch difference makes an AAA cup, 1/2 inch makes an AA cup, 1 inch makes an A cup, 2 inches make a B cup, and so on! So, if your back measurement is 30 inches and your bust is 31 inches, you would be a 30A.
