Dance Wear Import Companies United Kingdom

Looking for a company for dance sets similar to my pictures ({links below), in plain colours and in prints/fabrics of a similar type. Stretchy fabrics like spandex or lycra blends, lined or good quality, not thin. I require a sewn in label using a one-colour logo I will supply. I will consider existing lines that can be branded, or ODM lines. I am not able to supply patterns/designs beyond the guidance here. My order quantities will initially be 50 units per style. I require a mixture of sizes (to fit UK women– XS equivalent to EU size 34, and XL equivalent to EU size 42) and I will prioritise manufacturers that can also supply more than one colour or print per style. I will require a sample (paid) of each item I choose prior to ordering, to check sizing and quality. If you can help, please send images of any existing products like my examples. Please do not send general catalogues. If you do not have existing items but can make them, please advise on the time to create a digital sample for review, and show some choices of fabrics and colours/prints. Please advise guide price per unit for 50 units in one style in a run of sizes.
